Struct Formatter

pub struct Formatter<'a>(/* private fields */);

Allows formatting of fmt::Arguments into a raw buffer.

Fails if callers attempt to write more than will fit in the buffer.

Implementations

impl Formatter<'_>

pub fn new(buffer: &mut [u8]) -> Self

Create a new Self instance.

Methods from Deref<Target = RawFormatter>

pub fn bytes_written(&self) -> usize

Returns the number of bytes written to the formatter.

Trait Implementations

impl Deref for Formatter<'_>

type Target = RawFormatter

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Write for Formatter<'_>

fn write_str(&mut self, s: &str) -> Result

Writes a string slice into this writer, returning whether the write succeeded.

fn write_char(&mut self, c: char) -> Result<(), Error>

Writes a char into this writer, returning whether the write succeeded.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Glue for usage of the write! macro with implementors of this trait.
