### Start Xray from Inline JSON Configuration

Source: https://context7.com/xtls/libxray/llms.txt

Starts an Xray instance with an in-memory JSON configuration. This is useful when the configuration is constructed dynamically. The `datDir` must be provided.

```go
configJSON := `{
  "inbounds": [{"port": 1080, "protocol": "socks", "tag": "socks-in"}],
  "outbounds": [{"protocol": "freedom", "tag": "direct"}]
}`

type RunXrayFromJSONRequest struct {
    DatDir     string `json:"datDir"`
    ConfigJSON string `json:"configJSON"`
}
req := RunXrayFromJSONRequest{
    DatDir:     "/data/app/geo",
    ConfigJSON: configJSON,
}
reqBytes, _ := json.Marshal(req)
b64 := base64.StdEncoding.EncodeToString(reqBytes)

result := libXray.RunXrayFromJSON(b64)
// {"success":true}
```

  "tunPriority":  100,
  "dns":          "8.8.8.8:53",
  "bindInterface": "eth0",
  "datDir":       "/usr/local/share/xray",

```kotlin
// Kotlin (Android) — called via gomobile binding
class MyVpnService : VpnService() {
    fun startProxy() {
        val controller = object : LibXray.DialerController {
            override fun protectFd(fd: Int): Boolean = protect(fd)
        }
        LibXray.registerDialerController(controller)
        LibXray.registerListenerController(controller)

        val b64 = LibXray.newXrayRunRequest("/data/data/app/geo", "", "/data/data/app/config.json")
        LibXray.runXray(b64)
    }
}
```

--------------------------------

    DatDir     string `json:"datDir"`
    ConfigPath string `json:"configPath"`
}
req := RunXrayRequest{
    DatDir:     "/data/app/geo",
    ConfigPath: "/data/app/config.json",
}
reqBytes, _ := json.Marshal(req)
b64 := base64.StdEncoding.EncodeToString(reqBytes)

result := libXray.TestXray(b64)
decoded, _ := base64.StdEncoding.DecodeString(result)
// {"success":true}   — config is valid
// {"success":false,"error":"failed to parse config: ..."}  — invalid config

### Convert Xray JSON config to share links

Source: https://context7.com/xtls/libxray/llms.txt

Serializes an Xray JSON configuration into shareable URI links. The `sendThrough` field of each outbound is used as the link name/fragment. VMess outbounds produce VMessAEAD links.

```go
xrayJSON := `{
  "outbounds": [
    {
      "protocol": "vless",
      "sendThrough": "MyServer",
      "settings": {
        "address": "example.com", "port": 443,
        "id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
        "encryption": "none", "flow": "xtls-rprx-vision"
      },
      "streamSettings": {
        "network": "raw", "security": "reality",
        "realitySettings": {
          "fingerprint": "chrome", "serverName": "example.com",
          "publicKey": "...", "shortId": "abcdef12"
        }
      }
    }
  ]
}`

b64 := base64.StdEncoding.EncodeToString([]byte(xrayJSON))
result := libXray.ConvertXrayJsonToShareLinks(b64)
decoded, _ := base64.StdEncoding.DecodeString(result)
// {"success":true,"data":"vless://xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx@example.com:443?flow=xtls-rprx-vision&...#MyServer"}

### Override system DNS resolver

Source: https://context7.com/xtls/libxray/llms.txt

Replaces `net.DefaultResolver` so Go's DNS queries bypass the TUN interface. On Android, socket protection is applied; on Linux, interface binding is used. Use `ResetDns` to restore defaults.

```go
// Android: protect the DNS socket via the controller callback
dns.InitDns("8.8.8.8:53", func(fd uintptr) {
    vpnService.Protect(int(fd))
})

// Linux: bind DNS socket to a specific network interface
dns.InitDns("8.8.8.8:53", "eth0")

// Restore default resolver (e.g. when VPN stops)
dns.ResetDns()
```

--------------------------------

### ConvertXrayJsonToShareLinks

Source: https://context7.com/xtls/libxray/llms.txt

Serializes an Xray JSON configuration back into shareable links. Each outbound configuration is converted into its canonical URI format.

```APIDOC
## ConvertXrayJsonToShareLinks

### Description
Serializes an Xray JSON config back to share links. Each outbound in the Xray config is serialized to its canonical URI. VMess outbounds produce VMessAEAD links. The outbound's `sendThrough` field is used as the link name/fragment.

### Method
`libXray.ConvertXrayJsonToShareLinks(encodedXrayJson string)`

### Parameters
* `encodedXrayJson` (string) - Base64 encoded Xray JSON configuration.

### Response Example
```
{"success":true,"data":"vless://xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx@example.com:443?flow=xtls-rprx-vision&...#MyServer"}
```
```

--------------------------------

### InitDns / ResetDns

Source: https://context7.com/xtls/libxray/llms.txt

Initializes or resets the DNS resolver. On Android and Linux, this can override the system's default DNS resolver to bypass the TUN interface or bind to a specific interface.

```APIDOC
## InitDns / ResetDns

### Description
Overrides the system DNS resolver. Replaces `net.DefaultResolver` so that Go's DNS queries bypass the TUN interface and go directly to the specified server (with socket protection applied on Android, or interface binding on Linux).

### Method
`dns.InitDns(server string, callback interface{})
`dns.ResetDns()

### Parameters
* `server` (string) - The DNS server address and port (e.g., `"8.8.8.8:53"`).
* `callback` (interface{}) - Optional. On Android, this is a function to protect the DNS socket (`func(fd uintptr)`). On Linux, this can be the network interface name (string).

### Usage Examples
```go
// Android: protect the DNS socket via the controller callback
dns.InitDns("8.8.8.8:53", func(fd uintptr) {
    vpnService.Protect(int(fd))
})

// Linux: bind DNS socket to a specific network interface
dns.InitDns("8.8.8.8:53", "eth0")

// Restore default resolver (e.g. when VPN stops)
dns.ResetDns()
```
```

### Unified Base64-encoded JSON response

Source: https://context7.com/xtls/libxray/llms.txt

The `CallResponse[T]` structure serves as a unified response envelope for all wrapper functions in libXray. Responses are Base64 encoded JSON strings that can be decoded to check for success, retrieve data, or view error messages.

```APIDOC
## `CallResponse[T]` — Unified Base64-encoded JSON response

Every wrapper function returns a Base64 string that decodes to this structure. The helper `EncodeToBase64` is called internally by all wrappers.

### Go Decode Example

```go
import (
    "encoding/base64"
    "encoding/json"
    "fmt"
    "github.com/xtls/libxray/nodep"
)

// Decode any libXray response generically
func decodeResponse(b64Result string) {
    raw, err := base64.StdEncoding.DecodeString(b64Result)
    if err != nil {
        panic(err)
    }
    var resp struct {
        Success bool            `json:"success"`
        Data    json.RawMessage `json:"data,omitempty"`
        Err     string          `json:"error,omitempty"`
    }
    json.Unmarshal(raw, &resp)
    if resp.Success {
        fmt.Println("OK, data:", string(resp.Data))
    } else {
        fmt.Println("Error:", resp.Err)
    }
}

// Using the typed helper directly in library code:
var response nodep.CallResponse[int64]
encoded := response.EncodeToBase64(int64(342), nil)
// encoded → base64({"success":true,"data":342})
```
```
