Fields

lifetimes: HirVec<Lifetime>

🔬 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 lifetime parameters for this path segment.

types: HirVec<P<Ty>>

🔬 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 type parameters for this path segment, if present.

bindings: HirVec<TypeBinding>

🔬 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?

Bindings (equality constraints) on associated types, if present. E.g., Foo<A=Bar>.

parenthesized: bool

Were parameters written in parenthesized form Fn(T) -> U? This is required mostly for pretty-printing and diagnostics, but also for changing lifetime elision rules to be "function-like".
