### Compute CRC-64-ECMA checksum

Source: https://docs.rs/crc64fast/1.1.0/crc64fast/index.html

Demonstrates how to initialize a Digest, write data in chunks, and finalize the checksum calculation.

```rust
use crc64fast::Digest;

let mut c = Digest::new();
c.write(b"hello ");
c.write(b"world!");
let checksum = c.sum64();
assert_eq!(checksum, 0x8483_c0fa_3260_7d61);
```

### Digest::new()

Source: https://docs.rs/crc64fast

Creates a new Digest instance to begin an in-progress CRC-64 computation.

```APIDOC
## Digest::new()

### Description
Creates a new instance of the Digest struct to start a CRC-64-ECMA computation.

### Signature
`pub fn new() -> Digest`
```

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

### Digest::new

Source: https://docs.rs/crc64fast/1.1.0/crc64fast/index.html

Creates a new Digest instance to begin a CRC-64-ECMA computation.

```APIDOC
## Digest::new

### Description
Creates a new instance of the Digest struct to start an in-progress CRC-64 computation.

### Signature
`pub fn new() -> Digest`
```

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

### Digest::new()

Source: https://docs.rs/crc64fast/1.1.0/crc64fast/struct.Digest.html

Creates a new Digest instance. It automatically performs runtime CPU feature detection to select the most efficient algorithm.

```APIDOC
## pub fn new() -> Self

### Description
Creates a new `Digest` instance. It will perform runtime CPU feature detection to determine which algorithm to choose for optimal performance.

### Returns
- **Self** - A new instance of the Digest struct.
```

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

### Digest::new_table()

Source: https://docs.rs/crc64fast/1.1.0/crc64fast/struct.Digest.html

Creates a new Digest instance specifically using the table-based algorithm.

```APIDOC
## pub fn new_table() -> Self

### Description
Creates a new `Digest` instance using the table-based algorithm.

### Returns
- **Self** - A new instance of the Digest struct.
```

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

### Digest::write()

Source: https://docs.rs/crc64fast/1.1.0/crc64fast/struct.Digest.html

Writes data into the digest to update the CRC-64 calculation.

```APIDOC
## pub fn write(&mut self, bytes: &[u8])

### Description
Writes some data into the digest to update the ongoing CRC-64 computation.

### Parameters
- **bytes** (&[u8]) - The data to be processed by the digest.
```

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

### Digest::sum64()

Source: https://docs.rs/crc64fast/1.1.0/crc64fast/struct.Digest.html

Computes and returns the current CRC-64-ECMA value.

```APIDOC
## pub fn sum64(&self) -> u64

### Description
Computes the current CRC-64-ECMA value based on the data written so far.

### Returns
- **u64** - The calculated CRC-64-ECMA value.
```

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

### Digest::sum64

Source: https://docs.rs/crc64fast/1.1.0/crc64fast/index.html

Finalizes the computation and returns the resulting 64-bit CRC checksum.

```APIDOC
## Digest::sum64

### Description
Finalizes the current CRC-64 computation and returns the calculated checksum as a u64.

### Signature
`pub fn sum64(&self) -> u64`
```

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

### Digest::write

Source: https://docs.rs/crc64fast/1.1.0/crc64fast/index.html

Updates the current CRC-64 computation with the provided byte slice.

```APIDOC
## Digest::write

### Description
Updates the internal state of the Digest with the provided input bytes.

### Signature
`pub fn write(&mut self, bytes: &[u8])`
```
