Enum SourcePin 

pub enum SourcePin {
    Projected(Box<ProjectionManifest>),
    Journal(JournalAnchor),
    Authoritative(u64),
}

One exact source premise a result read.

Variants

Projected(Box<ProjectionManifest>)

An exact published projection generation.

Boxed: a manifest is far larger than the other two premises, and an unboxed variant would make every pin in a thirty-two-pin vector that size.

Journal(JournalAnchor)

An exact anchored journal prefix.

Authoritative(u64)

An authoritative revision.

Implementations

impl SourcePin

pub fn identity_bytes(&self) -> Vec<u8>

Returns the canonical identity this pin sorts by.

The rule matches the durable audit’s own: a variant tag, then each source’s identity as length-prefixed bytes. Two projected descriptors for one key, two anchors for one partition, and two authoritative revisions therefore compare equal and are refused rather than collapsed.
