Struct Encoder 

pub struct Encoder { /* private fields */ }

LAME Encoder.

Implementations

impl Encoder

pub fn sample_rate(&self) -> u32

Returns sample rate.

pub fn num_channels(&self) -> u8

Returns number of channels.

pub fn encode( &mut self, input: impl EncoderInput, output: &mut [MaybeUninit<u8>], ) -> Result<usize, EncodeError>

Attempts to encode PCM data, writing whatever available onto output buffer

Arguments:

• input - Data input. Can be MonoPcm, DualPcm or InterleavedPcm
• output - Output buffer to write into.

Result:

On success, returns number of bytes written (can be 0). Otherwise returns error indicating potential issue.

pub fn encode_to_vec( &mut self, input: impl EncoderInput, output: &mut Vec<u8>, ) -> Result<usize, EncodeError>

Attempts to encode PCM data, writing whatever available onto output buffer

output size is adjusted on success only

Refer for details to encode()

pub fn flush<T: EncoderFlush>( &mut self, output: &mut [MaybeUninit<u8>], ) -> Result<usize, EncodeError>

Attempts flush all data, writing whatever available onto output buffer Padding with 0 to complete MP3

Type:

• FlushNoGap - performs flush, using ancillary data to fill gaps;
• FlushGap - performs flush, padding with 0;

Arguments:

• output - Output buffer to write into. As it is final action, you need at least 7200 bytes to hold at MP3 data.

Result:

On success, returns number of bytes written (can be 0). Otherwise returns error indicating potential issue.

pub fn flush_to_vec<T: EncoderFlush>( &mut self, output: &mut Vec<u8>, ) -> Result<usize, EncodeError>

Attempts flush all data, writing whatever available onto output buffer.

output size is adjusted on success only

Refer for details to flush()
