Struct ExactPcmAdapter

pub struct ExactPcmAdapter { /* private fields */ }

A validated, stateless mapping from canonical source integers to bytes.

No source rate, precision, speaker position or normalized sample value is changed. Output integers are full-width PCM: widening shifts source values towards the most significant bit, rather than merely sign-extending them. Float scaling is exact for every source value in the 16/24-bit profile.

Implementations

impl ExactPcmAdapter

pub fn new( source: IntegerPcmFormat, output: ExactOutputFormat, ) -> Result<Self, ExactOutputError>

Refuse rate/layout conversion and unknown or insufficient precision.

pub fn source_format(self) -> IntegerPcmFormat

Original unscaled signed source format accepted by this adapter.

pub fn output_format(self) -> ExactOutputFormat

Software output representation accepted by this adapter.

pub fn encode_block( self, samples: &[i32], encoded: &mut Vec<u8>, ) -> Result<usize, ExactOutputError>

Replace encoded with one bounded, complete interleaved block.

Return the encoded frame count. An empty block produces no bytes. All source samples, frame alignment and capacity are validated before the existing encoded bytes are modified. Allocation is permitted here, so callers must encode outside the output callback and may reuse capacity.

Trait Implementations

impl Clone for ExactPcmAdapter

fn clone(&self) -> ExactPcmAdapter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExactPcmAdapter

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

Formats the value using the given formatter.

impl PartialEq for ExactPcmAdapter

fn eq(&self, other: &ExactPcmAdapter) -> 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.
