pub struct LayeredWriter<Inner> { /* fields omitted */ }
Expand description

Adapts a std::io::Write to implement WriteLayered.

Implementations

impl<Inner: Write> LayeredWriter<Inner>[src]

pub fn new(inner: Inner) -> Self[src]

Construct a new LayeredWriter which wraps inner.

pub fn get_ref(&self) -> &Inner[src]

Gets a reference to the underlying writer.

pub fn get_mut(&mut self) -> &mut Inner[src]

Gets a mutable reference to the underlying writer.

It is inadvisable to directly write to the underlying writer.

Close this LayeredWriter and return the inner stream.

pub fn abandon_into_inner(self) -> Option<Inner>[src]

Consume this LayeredWriter and return the inner stream.
