Struct CompressionSession 

Source 
pub struct CompressionSession { /* private fields */ }
Expand description

The compression schemes registered on a session, in registration order.

BtrBlocksCompressorBuilder::from_session starts from these schemes. Registration order is the compressor’s tie-break order, so that scheme selection is deterministic.

Default registers every built-in scheme, including Delta and the feature-gated Pco and Zstd schemes. The builder’s preset decides which of them a compressor uses.

Implementations§

Source§

impl CompressionSession

Source

pub fn register(&mut self, scheme: &'static dyn Scheme)

Registers a compression scheme after the ones already registered.

This allows encoding crates outside of vortex-btrblocks to make their own schemes available to compressors built from the session.

§Panics

Panics if a scheme with the same SchemeId is already registered.

Source

pub fn schemes(&self) -> &[&'static dyn Scheme]

Returns the registered schemes in registration order.
