Struct core::num::fmt::Formatted

pub struct Formatted<'a> {
    pub sign: &'static str,
    pub parts: &'a [Part<'a>],
}

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

Formatted result containing one or more parts. This can be written to the byte buffer or converted to the allocated string.

Fields

sign: &'static str

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

A byte slice representing a sign, either "", "-" or "+".

parts: &'a [Part<'a>]

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

Formatted parts to be rendered after a sign and optional zero padding.

Implementations

impl<'a> Formatted<'a>

pub fn len(&self) -> usize

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

Returns the exact byte length of combined formatted result.

pub fn write(&self, out: &mut [u8]) -> Option<usize>

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

Writes all formatted parts into the supplied buffer. Returns the number of written bytes, or None if the buffer is not enough. (It may still leave partially written bytes in the buffer; do not rely on that.)

Trait Implementations

impl<'a> Clone for Formatted<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.
