§args: &'hir [GenericArg<'hir>]

The generic arguments for this path segment.

§bindings: &'hir [TypeBinding<'hir>]

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

§parenthesized: bool

Were arguments 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”.

§span_ext: Span

The span encompassing arguments and the surrounding brackets <> or () Foo<A, B, AssocTy = D> Fn(T, U, V) -> W ^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^ Note that this may be:

  • empty, if there are no generic brackets (but there may be hidden lifetimes)
  • dummy, if this was generated while desugaring


This function returns the number of type and const generic params. It should only be used for diagnostics.

The span encompassing the text inside the surrounding brackets. It will also include bindings if they aren’t in the form -> Ret Returns None if the span is empty (e.g. no brackets) or dummy

Returns span encompassing arguments and their surrounding <> or ()

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.
