Struct CompressorContext 

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

Context passed through recursive compression calls.

Tracks the cascade history (which schemes and child indices have been applied in the current chain) so the compressor can enforce exclusion rules and prevent cycles.

Implementations§

Source§

impl CompressorContext

Source

pub fn is_sample(&self) -> bool

Whether this context is for sample compression (ratio estimation).

Source

pub fn merged_stats_options(&self) -> GenerateStatsOptions

Returns the merged stats generation options for this compression site.

Source

pub fn cascade_history(&self) -> &[(SchemeId, usize)]

Returns the cascade chain of (scheme_id, child_index) pairs.

Source

pub fn finished_cascading(&self) -> bool

Whether cascading is exhausted (no further cascade levels allowed).

This should only be used in the implementation of a Scheme if the scheme knows that it’s child must be compressed for it to make any sense being chosen.

Source

pub fn as_leaf(self) -> Self

Returns a context that disallows further cascading.
