Struct DeferredMetadata

Source

pub struct DeferredMetadata(/* private fields */);

Expand description

A metadata payload whose final form needs the written (deduplicated) counts. See IntoMetadata.

Implementations§

Source §

impl DeferredMetadata

Source

pub fn new(f: impl FnOnce(FinalCounts) -> Vec<u8> + 'static) -> Self

Defer f until the indexes are built and the true counts are known.

Source

pub fn none() -> Self

No metadata section — byte-identical to a metadata-free build. Lets one match arm opt out while the other defers, without a type mismatch.
