Struct Formatter

pub struct Formatter<'f, 'a> { /* private fields */ }

A wrapper around a fmt::Formatter which provides checksumming ability.

Implementations

impl<'f, 'a> Formatter<'f, 'a>

pub fn new(f: &'f mut Formatter<'a>) -> Self

Contructs a new Formatter, wrapping a given fmt::Formatter.

pub fn write_checksum(&mut self) -> Result

Writes the checksum into the underlying fmt::Formatter.

pub fn write_checksum_if_not_alt(&mut self) -> Result

Writes the checksum into the underlying fmt::Formatter, unless it has “alternate” display on.

Trait Implementations

impl<'f, 'a> Write for Formatter<'f, 'a>

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.
