Struct CodecInfo 

pub struct CodecInfo {
    pub sample_rate: u32,
    pub frame_rate: f32,
    pub hop_length: usize,
    pub channels: usize,
    pub max_quantizers: usize,
    pub codebook_size: usize,
}

Static description of a codec — enough to reason about rate, framing, and bitrate without touching a concrete config struct.

Fields

sample_rate: u32

Audio sample rate (Hz) the codec consumes/produces.

frame_rate: f32

Codec frames per second (Hz) — e.g. Mimi 12.5, DAC sample_rate/hop.

hop_length: usize

PCM samples per codec frame (sample_rate / frame_rate).

channels: usize

Audio channels (1 for the mono codecs here).

max_quantizers: usize

Codebooks (quantizers) available at full rate.

codebook_size: usize

Entries per codebook.

Implementations

impl CodecInfo

pub fn bits_per_codebook(&self) -> f32

Bits carried by one codebook index (log2(codebook_size)).

pub fn bits_per_second_per_codebook(&self) -> f32

Bits/sec contributed by a single codebook at this frame rate.

pub fn bitrate_bps(&self, num_quantizers: Option<usize>) -> f32

Nominal bitrate (bits/sec) for num_quantizers codebooks (default: all).

pub fn quantizers_for_bitrate(&self, target_bps: f32) -> usize

The largest codebook count whose nominal bitrate stays at or below target_bps, clamped to [1, max_quantizers]. Codec-agnostic bitrate control: callers pass a bitrate, codecs pick the quantizer count.

pub fn frames_for_samples(&self, num_samples: usize) -> usize

Number of codec frames produced for num_samples PCM samples.

Trait Implementations

impl Clone for CodecInfo

fn clone(&self) -> CodecInfo

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for CodecInfo

impl Debug for CodecInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for CodecInfo

fn eq(&self, other: &CodecInfo) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
