Methods

impl<'a> Format<'a>

pub fn translate(&self) -> Option<String>

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Translate this directive into an equivalent Rust formatting directive.

Returns None in cases where the printf directive does not have an exact Rust equivalent, rather than guessing.

Trait Implementations

impl<'a> Clone for Format<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> PartialEq for Format<'a>

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

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

fn ne(&self, other: &Format<'a>) -> bool

This method tests for !=.

impl<'a> Debug for Format<'a>

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

Formats the value using the given formatter.
