Struct rustc::hir::ItemLocalId[][src]

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

An ItemLocalId uniquely identifies something within a given "item-like", that is within a hir::Item, hir::TraitItem, or hir::ImplItem. There is no guarantee that the numerical value of a given ItemLocalId corresponds to the node's position within the owning item in any way, but there is a guarantee that the LocalItemIds within an owner occupy a dense range of integers starting at zero, so a mapping that maps all or most nodes within an "item-like" to something else can be implement by a Vec instead of a tree or hash map.
