Struct PreparedCodec 

pub struct PreparedCodec { /* private fields */ }

Pre-built compress/decompress session.

Construct once with PreparedCodec::new, then pass to [Codec::compress_prepared] / [Codec::decompress_prepared_into] for each vector. The RotationMatrix inside is computed exactly once.

Implementations

impl PreparedCodec

pub fn new(config: CodecConfig, codebook: Codebook) -> Result<Self, CodecError>

Build from a validated config and trained codebook.

The rotation matrix is computed exactly once.

Errors

CodecError::CodebookIncompatible if codebook.bit_width() != config.bit_width().

pub const fn config(&self) -> &CodecConfig

The CodecConfig that defines this session.

pub const fn codebook(&self) -> &Codebook

The trained Codebook for this session.

pub const fn rotation(&self) -> &RotationMatrix

The pre-built RotationMatrix — computed once at construction.

pub fn set_gpu_state(&mut self, state: Box<dyn Any + Send + Sync>)

Attach opaque GPU state.

Called by GPU backends — do not call from application code.

pub fn has_gpu_state(&self) -> bool

true if a GPU backend has attached device-resident state.

pub fn gpu_state(&self) -> Option<&(dyn Any + Send + Sync)>

Borrow the attached GPU state, if any.

Called by GPU backends to retrieve device-resident buffers. Application code should not call this directly.
