Struct Decoder 

pub struct Decoder<R> { /* private fields */ }

Streaming AHX decoder with fixed synthesis and PCM arrays, available with std.

No allocation or seeking is performed by this decoder. Wrap files in std::io::BufReader for efficient small reads. Reader-owned buffering and output handling are outside the decoder’s allocation guarantee.

Implementations

impl<R> Decoder<R>

pub const fn metadata(&self) -> Metadata

Validated file timing and header layout.

pub const fn state(&self) -> DecoderState

Current decoding progress, successful completion, or terminal failure.

pub fn into_inner(self) -> R

Recover the reader at its current position, without rewinding.

impl<R: Read> Decoder<R>

pub fn new(reader: R) -> Result<Self, Error>

Validate the header and initialize fixed-size storage without allocating.

pub fn next_block(&mut self) -> Result<Option<&[i16]>, Error>

Decode up to SAMPLES_PER_FRAME mono PCM16 elements into borrowed storage.

No startup samples are discarded and no resampling occurs. The final block is trimmed to the declared duration after validating the footer. Errors invalidate the reader; calls after an error return Error::Failed. An unwinding panic in caller I/O also leaves it failed. Calls after successful EOF return None without reading further input.

Trait Implementations

impl<R> Debug for Decoder<R>

Available on crate feature std only.

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

Formats the value using the given formatter.
