Summarizes information

Variants

`Arg(String, String)`

An argument of non-tuple type. Parameters are (name, ty)

`Tuple(Option, Vec<(String, String)>)`

An argument of tuple type. For a “found” argument, the span is the location in the source of the pattern. For an “expected” argument, it will be None. The vector is a list of (name, ty) strings for the components of the tuple.

Implementations

source

impl ArgKind

source

fn empty() -> ArgKind

source

pub fn from_expected_ty(t: Ty<'_>, span: Option) -> ArgKind

Creates an ArgKind from the expected type of an argument. It has no name (_) and an optional source span.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
