Enum rustc_parse_format::Count

source ·

pub enum Count<'a> {
    CountIs(usize),
    CountIsName(&'a str, InnerSpan),
    CountIsParam(usize),
    CountIsStar(usize),

Expand description

A count is used for the precision and width parameters of an integer, and can reference either an argument or a literal integer.

Variants

`CountIs(usize)`

The count is specified explicitly.

`CountIsName(&'a str, InnerSpan)`

The count is specified by the argument with the given name.

`CountIsParam(usize)`

The count is specified by the argument at the given index.

`CountIsStar(usize)`

The count is specified by a star (like in {:.*}) that refers to the argument at the given index.

`CountImplied`

The count is implied and cannot be explicitly specified.

Trait Implementations

impl<'a> Clone for Count<'a>

source

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

Returns a copy of the value. Read more

1.0.0 · source

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

Performs copy-assignment from source. Read more

source

impl<'a> Debug for Count<'a>

Formats the value using the given formatter. Read more

source

impl<'a> PartialEq<Count<'a>> for Count<'a>

source

fn eq(&self, other: &Count<'a>) -> bool

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

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.
