Variants

type_of(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?

Records the type of every item.

generics_of(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?

Maps from the def-id of an item (trait/struct/enum/fn) to its associated generics and predicates.

predicates_of(DefId)

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

Maps from the def-id of a trait to the list of super-predicates. This is a subset of the full list of predicates. We store these in a separate map because we must evaluate them even during type conversion, often before the full predicates are available (note that supertraits have additional acyclicity requirements).
