Struct Diff 

pub struct Diff {
    pub added: Vec<Component>,
    pub removed: Vec<Component>,
    pub changed: Vec<ComponentChange>,
    pub edge_diffs: Vec<EdgeDiff>,
    pub metadata_changed: bool,
    pub old_total: usize,
    pub new_total: usize,
    pub unchanged: usize,
    pub component_names: BTreeMap<ComponentId, String>,
}

The result of comparing two SBOMs.

Contains lists of added, removed, and changed components, as well as dependency edge changes.

Fields

added: Vec<Component>

Components present in the new SBOM but not the old.

removed: Vec<Component>

Components present in the old SBOM but not the new.

changed: Vec<ComponentChange>

Components present in both with field-level changes.

edge_diffs: Vec<EdgeDiff>

Dependency edge changes between components.

metadata_changed: bool

Whether document metadata differs (usually ignored).

old_total: usize

Total number of components in the old SBOM.

new_total: usize

Total number of components in the new SBOM.

unchanged: usize

Number of components present in both SBOMs with no changes.

component_names: BTreeMap<ComponentId, String>

Human-readable display names for component IDs that appear in edge diffs.

Maps hash-based IDs (h:...) to name@version or name so that edge diff output is readable without cross-referencing the full component list.

Implementations

impl Diff

pub fn is_empty(&self) -> bool

Returns true if the diff contains no changes of any kind.

pub fn display_name<'a>(&'a self, id: &'a ComponentId) -> &'a str

Returns a human-readable display name for a component ID.

Looks up the ID in component_names; falls back to the raw ID string.

pub fn ecosystem_breakdown(&self) -> BTreeMap<String, EcosystemCounts>

Groups added/removed/changed counts by package ecosystem.

Components without an ecosystem are grouped under "unknown".

pub fn group_by_ecosystem(&self) -> GroupedDiff

Groups the full diff by ecosystem, returning per-ecosystem slices.

Components without an ecosystem are grouped under "unknown".

pub fn into_group_by_ecosystem(self) -> GroupedDiff

Consuming variant of group_by_ecosystem that moves components instead of cloning them.

Trait Implementations

impl Clone for Diff

fn clone(&self) -> Diff

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Diff

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Diff

fn default() -> Diff

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Diff

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Diff

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
