Module scheme 

Everything a scheme author implements or receives: the Scheme trait, exclusion rules, compression estimates, and the compression context.

Structs

AncestorExclusion

Pull rule: declared by a scheme to exclude itself when the specified ancestor is in the cascade chain.

CompressorContext

Context passed through recursive compression calls.

DescendantExclusion

Push rule: declared by a cascading scheme to exclude another scheme from the subtree rooted at the specified children.

SchemeId

Unique identifier for a compression scheme.

Enums

ChildSelection

Selects which children of a cascading scheme a rule applies to.

CompressionEstimate

The result of a Scheme’s compression ratio estimation.

DeferredEstimate

Deferred work that can resolve to a terminal EstimateVerdict.

EstimateScore

Ranked estimate used for comparing non-terminal compression candidates.

EstimateVerdict

The terminal answer to a compression estimate request.

Constants

MAX_CASCADE

Maximum cascade depth for compression.

Traits

Scheme

A single compression encoding that the CascadingCompressor can select from.

SchemeExt

Extension trait providing id for all Scheme implementors.

Type Aliases

EstimateFn

Closure type for DeferredEstimate::Callback.
