Summarizes information

Variants

Arg(String, String)

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

Tuple Fields of Arg

0: String1: String

Tuple(Option<Span>, 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.

Tuple Fields of Tuple

0: Option<Span>1: Vec<(String, String)>

Implementations

impl ArgKind

fn empty() -> ArgKind

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

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

Trait Implementations

impl Clone for ArgKind

fn clone(&self) -> ArgKind

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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.
