Struct G711Codec 

pub struct G711Codec { /* private fields */ }

G.711 codec implementation

Implementations

impl G711Codec

pub const fn new(variant: G711Variant) -> Self

Create a new G.711 codec with the specified variant

pub fn new_with_config( variant: G711Variant, config: CodecConfig, ) -> Result<Self, CodecError>

Create a new G.711 codec with configuration

Errors

Returns an error when the configuration uses a sample rate, channel count, or frame duration unsupported by G.711.

pub fn new_pcmu(config: CodecConfig) -> Result<Self, CodecError>

Create a new G.711 μ-law (PCMU) codec

Errors

Returns an error when config is not a supported G.711 configuration.

pub fn new_pcma(config: CodecConfig) -> Result<Self, CodecError>

Create a new G.711 A-law (PCMA) codec

Errors

Returns an error when config is not a supported G.711 configuration.

pub const fn variant(&self) -> G711Variant

Get the codec variant

pub fn compress(&self, samples: &[i16]) -> Result<Vec<u8>, CodecError>

Compress samples using the configured variant

Errors

This implementation is infallible; the result type is retained for API compatibility with other codecs.

pub fn expand(&self, compressed: &[u8]) -> Result<Vec<i16>, CodecError>

Expand samples using the configured variant

Errors

This implementation is infallible; the result type is retained for API compatibility with other codecs.

pub fn compress_alaw(&self, samples: &[i16]) -> Result<Vec<u8>, CodecError>

Compress samples using A-law

Errors

This implementation is infallible; the result type is retained for API compatibility.

pub fn expand_alaw(&self, compressed: &[u8]) -> Result<Vec<i16>, CodecError>

Expand A-law samples

Errors

This implementation is infallible; the result type is retained for API compatibility.

pub fn compress_ulaw(&self, samples: &[i16]) -> Result<Vec<u8>, CodecError>

Compress samples using μ-law

Errors

This implementation is infallible; the result type is retained for API compatibility.

pub fn expand_ulaw(&self, compressed: &[u8]) -> Result<Vec<i16>, CodecError>

Expand μ-law samples

Errors

This implementation is infallible; the result type is retained for API compatibility.
