Struct Output 

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

Where an engine writes: the reply body, reused between requests, with a size budget.

Implementations

impl<'a> Output<'a>

pub fn new(buf: &'a mut Vec<u8>, limit: usize) -> Self

An output over buf, refusing to grow past limit bytes.

pub fn write(&mut self, bytes: &[u8]) -> Result<(), RenderError>

Appends bytes.

Errors

render.too_large when the page would pass the budget.

pub fn write_str(&mut self, s: &str) -> Result<(), RenderError>

Appends a string.

Errors

As write.

pub fn buffer(&mut self) -> &mut Vec<u8>

The buffer itself, for an engine that writes into a Vec<u8>. The budget is checked when the engine returns: a page past it is refused with render.too_large.

pub fn len(&self) -> usize

Bytes written so far.

pub fn is_empty(&self) -> bool

Whether nothing was written yet.

pub fn remaining(&self) -> usize

The bytes still allowed.
