Struct RelationOccurrence 

pub struct RelationOccurrence { /* private fields */ }

One exact source occurrence supporting a logical relationship.

Implementations

impl RelationOccurrence

pub fn new( relation: &LogicalRelation, file: RepositoryFilePath, span: SourceSpan, generation: IndexGeneration, ) -> Result<Self, GraphContractError>

Construct one source occurrence for a logical relation.

Errors

Returns an error when the occurrence and relation generations differ.

pub const fn relation(&self) -> &LogicalRelationKey

Borrow the supported logical-relation key.

pub const fn file(&self) -> &RepositoryFilePath

Borrow the repository-local source file.

pub const fn span(&self) -> SourceSpan

Return the exact supporting source span.

pub const fn generation(&self) -> IndexGeneration

Return the complete generation containing this occurrence.

Trait Implementations

impl Clone for RelationOccurrence

fn clone(&self) -> RelationOccurrence

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RelationOccurrence

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

Formats the value using the given formatter.

impl PartialEq for RelationOccurrence

fn eq(&self, other: &RelationOccurrence) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for RelationOccurrence

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
