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.

predicates_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 the predicates (where clauses) that must be proven true in order to reference it. This is almost always the "predicates query" that you want.

predicates_of builds on predicates_defined_on -- in fact, it is almost always the same as that query, except for the case of traits. For traits, predicates_of contains an additional Self: Trait<...> predicate that users don't actually write. This reflects the fact that to invoke the trait (e.g., via Default::default) you must supply types that actually implement the trait. (However, this extra predicate gets in the way of some checks, which are intended to operate over only the actual where-clauses written by the user.)

predicates_defined_on(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 the predicates (where clauses) directly defined on it. This is equal to the explicit_predicates_of predicates plus the inferred_outlives_of predicates.

explicit_predicates_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?

Returns the predicates written explicit by the user.

inferred_outlives_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?

Returns the inferred outlives predicates (e.g., for struct Foo<'a, T> { x: &'a T }, this would return T: 'a).

super_predicates_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 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).

type_param_predicates((DefId, 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?

To avoid cycles within the predicates of a single item we compute per-type-parameter predicates for resolving T::AssocTy.
