Struct TextOutput 

pub struct TextOutput<'a, W> { /* private fields */ }

Adapts a byte writer for allocation-free std::fmt::Write formatting.

Formatting APIs expose only fmt::Error; this adapter retains the original I/O error so callers can recover it with TextOutput::finish.

Implementations

impl<'a, W> TextOutput<'a, W>

pub const fn new(output: &'a mut W) -> Self

Borrows a byte destination without adding a buffer.

pub fn finish(self) -> Result<()>

Returns the first destination failure, if any.

Errors

Returns the original I/O error retained while formatting.

Trait Implementations

impl<W> Debug for TextOutput<'_, W>

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<W: Write> Write for TextOutput<'_, W>

fn write_str(&mut self, text: &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.
