Struct StringBuilder 

pub struct StringBuilder<'buffer> { /* private fields */ }

A helper type to safely build a string in the buffer from multiple pieces.

It takes an exclusive reference to the buffer and clears everything in the buffer before we start building. This guarantees that upon finishing, the buffer contains only what we wrote to it.

Implementations

impl<'buffer> StringBuilder<'buffer>

pub fn new(buffer: &'buffer mut Buffer) -> Self

pub fn push_str(&mut self, src: &str)

pub fn push_char(&mut self, c: char)

pub fn push_superchar(&mut self, sc: SuperChar)

pub fn finish(self, arena: &Arena) -> &str

pub fn is_empty(&self) -> bool

Trait Implementations

impl<'buffer> Debug for StringBuilder<'buffer>

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

Formats the value using the given formatter.

impl Write for StringBuilder<'_>

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.
