Struct SectionHashes 

pub struct SectionHashes {
    pub components: u64,
    pub dependencies: u64,
    pub licenses: u64,
    pub vulnerabilities: u64,
}

Section-level hashes for incremental change detection.

Fields

components: u64

Hash of all components

dependencies: u64

Hash of all dependency edges

licenses: u64

Hash of all licenses

vulnerabilities: u64

Hash of all vulnerabilities

Implementations

impl SectionHashes

pub fn from_sbom(sbom: &NormalizedSbom) -> Self

Compute section hashes for an SBOM.

CORRECTNESS CONTRACT: each section hash must cover EVERY input its section computer reads — diff_sections splices the previous pair’s section verbatim whenever a hash is unchanged, so an uncovered field silently serves a stale diff (a vulnerability moving between components and an edge scope flip both did exactly that). A hash that covers too much only costs a spurious recompute; one that covers too little is a correctness bug.

Hashes are order-sensitive by design: reordering only ever produces a false “changed”, which is safe.

pub const fn changed_sections(&self, other: &Self) -> ChangedSections

Check which sections differ between two hash sets.
