pub struct AutoFinishEncoder<'a, W: Write, F: FnMut(Result<W>) = Box<dyn Send + FnMut(Result<W>)>> { /* private fields */ }
Expand description

A wrapper around an Encoder<W> that finishes the stream on drop.

This can be created by the auto_finish() method on the Encoder.

Implementations§

source§

impl<'a, W: Write, F: FnMut(Result<W>)> AutoFinishEncoder<'a, W, F>

source

pub fn get_ref(&self) -> &W

Acquires a reference to the underlying writer.

source

pub fn get_mut(&mut self) -> &mut W

Acquires a mutable reference to the underlying writer.

Note that mutation of the writer may result in surprising results if this encoder is continued to be used.

Mostly used for testing purposes.
