Implementations

impl ApeInfo

pub fn frame_samples(&self, frame_idx: u32) -> u32

Number of samples (blocks) in a given frame.

pub fn generate_wav_header(&self) -> Vec<u8>

Generate a standard 44-byte RIFF/WAVE header for the decoded audio.

Use this when ApeDecoder::wav_header_data() returns None (the CREATE_WAV_HEADER flag was set, meaning the original header was not stored). Combine with decoded PCM to produce a valid WAV file:

let header = decoder.info().generate_wav_header();
let pcm = decoder.decode_all()?;
output.write_all(&header)?;
output.write_all(&pcm)?;

Trait Implementations

impl Clone for ApeInfo

fn clone(&self) -> ApeInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ApeInfo

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

Formats the value using the given formatter.
