Struct BoxedResampler 

pub struct BoxedResampler { /* private fields */ }

Self-contained Resampler that owns its coefficient buffer (std only).

Resampler borrows a ~24 KB caller-provided coefficient slice, which makes it awkward to store as a long-lived struct field (the buffer must outlive the resampler). BoxedResampler heap-allocates the coefficients once and keeps them alive for the resampler’s whole lifetime, restoring the pre-0.4 ergonomic new(input_rate, output_rate) + resample(..) call shape for std users that hold resamplers in struct fields.

Implementations

impl BoxedResampler

pub fn new(input_rate: usize, output_rate: usize) -> Result<Self, CodecError>

Create a resampler that owns its polyphase filter coefficients.

Fails only for zero rates (the coefficient buffer is always sized correctly internally).

pub fn resample(&mut self, input: &[Sample]) -> PcmBuf

Convenience wrapper that allocates the output buffer.

pub fn resample_into( &mut self, input: &[Sample], out: &mut [Sample], ) -> Result<usize, CodecError>

Resample into a caller-provided buffer (no allocation).

pub fn max_output_samples(&self, n_input: usize) -> usize

Upper bound on the output sample count for n_input input samples.

pub fn reset(&mut self)

Reset the resampling history (e.g. after a source discontinuity).
