Struct rustc_builtin_macros::format::ast::FormatArgPosition

pub struct FormatArgPosition {
    pub index: Result<usize, usize>,
    pub kind: FormatArgPositionKind,
    pub span: Option<Span>,
}

Fields

index: Result<usize, usize>

Which argument this position refers to (Ok), or would’ve referred to if it existed (Err).

kind: FormatArgPositionKind

What kind of position this is. See FormatArgPositionKind.

span: Option<Span>

The span of the name or number.

Trait Implementations

impl Clone for FormatArgPosition

fn clone(&self) -> FormatArgPosition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FormatArgPosition

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<FormatArgPosition> for FormatArgPosition

fn eq(&self, other: &FormatArgPosition) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for FormatArgPosition

impl StructuralEq for FormatArgPosition

impl StructuralPartialEq for FormatArgPosition

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.
