Struct ReferenceIndex 

pub struct ReferenceIndex { /* private fields */ }

The references of one load, interned, with lookups by target and by holder; see the module documentation for what is a reference.

Every reference is kept once. ReferenceIndex::iter and ReferenceIndex::to give references grouped by target, targets in a fixed order (by kind, then by their identities’ bytes), and within a target in source order: by file path, then by span. ReferenceIndex::from gives a holder’s references in source order. Both lookups are binary searches, so their cost does not grow with the references they skip.

Implementations

impl ReferenceIndex

pub fn len(&self) -> usize

How many references there are.

pub fn is_empty(&self) -> bool

Whether there are none.

pub fn iter(&self) -> impl ExactSizeIterator<Item = Reference<'_>> + '_

Every reference, grouped by target, each group in source order.

pub fn to( &self, target: Target<'_>, ) -> impl ExactSizeIterator<Item = Reference<'_>> + '_

The references to target, in source order: none when nothing names it, or when it does not exist.

pub fn from( &self, holder: Holder<'_>, ) -> impl ExactSizeIterator<Item = Reference<'_>> + '_

The references holder holds, in source order. An object’s are its own, not its inventory’s; a chunk’s are its palettes’, not its objects’.

Trait Implementations
