### Internal Helper Functions - Rust

Source: https://github.com/phoenix-protocol-group/phoenix-nft-marketplace/blob/master/contracts/deployer/README.md

These are internal helper functions used within the Collections Deployer contract to manage state and data storage.

```Rust
fn set_initialized(env: &Env)
fn set_wasm_hash(env: &Env, hash: &BytesN<32>)
fn get_wasm_hash(env: &Env) -> BytesN<32>
fn save_collection_with_generic_key(env: &Env, name: String)
fn save_collection_with_admin_address_as_key(env: &Env, name: String, admin: Address)
```

### Defining Internal Structs for Collection Contract in Rust

Source: https://github.com/phoenix-protocol-group/phoenix-nft-marketplace/blob/master/contracts/collections/README.md

Defines the internal data structures used within the collection contract. `Config` stores basic collection metadata like name and symbol. `URIValue` is used to represent URIs associated with tokens or the collection. `OperatorApprovalKey` is a helper struct for managing operator approvals.

```Rust
pub struct Config {
    pub name: String,
    pub symbol: String,
}

pub struct URIValue {
    pub uri: Bytes,
}

pub struct OperatorApprovalKey {
    pub owner: Address,
    pub operator: Address,
}
```
