Struct Adapter

pub(crate) struct Adapter<W>
where
    W: FnMut(&[u8]) -> Result<()>,
{
    writer: W,
    error: Result<()>,
}

A shim which allows a std::io::Write to be implemented in terms of a std::fmt::Write

This saves off I/O errors. instead of discarding them

Fields

writer: W

error: Result<()>

Implementations

impl<W> Adapter<W>

where W: FnMut(&[u8]) -> Result<()>,

pub(crate) fn new(writer: W) -> Self

pub(crate) fn write_fmt(self, fmt: Arguments<'_>) -> Result<()>

Trait Implementations

impl<W> Write for Adapter<W>

where W: FnMut(&[u8]) -> Result<()>,

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.
