Struct email_encoding::headers::writer::EmailWriter

pub struct EmailWriter<'a> { /* private fields */ }

Wrapper around Write that remembers the length of the last line written to it.

Implementations

impl<'a> EmailWriter<'a>

pub fn new(
    writer: &'a mut dyn Write,
    line_len: usize,
    write_space_on_next_write: bool
) -> Self

Construct a new EmailWriter.

• line_len is the length of the last line in writer.
• write_space_on_next_write is whether the writer must go to a new line when writing it’s first character

pub fn new_line(&mut self) -> Result

Go to a new line and reset the line_len to 0.

pub fn space(&mut self)

Write a space which might get wrapped to a new line on the next write.

This method shouldn’t be called multiple times consecutively, and will panic if debug assertions are on.

pub fn line_len(&self) -> usize

Get the length in bytes of the last line written to the inner writer.

pub fn folding<'b>(&'b mut self) -> FoldingEmailWriter<'a, 'b>

Get a Writer which automatically line folds text written to it.

Trait Implementations

impl<'a> Write for EmailWriter<'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

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.
