Fields

local_id_root: Option<DefId>

🔬 This is a nightly-only experimental API. (rustc_private)

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?

The HirId::owner all ItemLocalIds in this table are relative to.

upvar_capture_map: UpvarCaptureMap<'tcx>

Borrows

used_trait_imports: Rc<DefIdSet>

🔬 This is a nightly-only experimental API. (rustc_private)

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?

Set of trait imports actually used in the method resolution. This is used for warning unused imports. During type checking, this Rc should not be cloned: it must have a ref-count of 1 so that we can insert things into the set mutably.

tainted_by_errors: bool

🔬 This is a nightly-only experimental API. (rustc_private)

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?

If any errors occurred while type-checking this body, this field will be set to true.

free_region_map: FreeRegionMap<'tcx>

🔬 This is a nightly-only experimental API. (rustc_private)

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?

Stores the free-region relationships that were deduced from its where clauses and parameter types. These are then read-again by borrowck.
