Methods

impl PathParameters

fn none() -> PathParameters

fn is_empty(&self) -> bool

fn has_lifetimes(&self) -> bool

fn has_types(&self) -> bool

fn types(&self) -> Vec<&P<Ty>>

Unstable (rustc_private)

Returns the types that the user wrote. Note that these do not necessarily map to the type parameters in the parenthesized case.
