Enum rustc_parse_format::Piece

pub enum Piece<'a> {
    String(&'a str),
    NextArgument(Box<Argument<'a>>),
}

A piece is a portion of the format string which represents the next part to emit. These are emitted as a stream by the Parser class.

Variants

String(&'a str)

A literal string which should directly be emitted

NextArgument(Box<Argument<'a>>)

This describes that formatting should process the next argument (as specified inside) for emission.

Trait Implementations

impl<'a> Clone for Piece<'a>

fn clone(&self) -> Piece<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Piece<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq<Piece<'a>> for Piece<'a>

fn eq(&self, other: &Piece<'a>) -> 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<'a> StructuralPartialEq for Piece<'a>

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.
