Struct layered_io::LayeredDuplexer[][src]

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

Adapts an Read + Write to implement DuplexLayered.

Implementations

Construct a new LayeredDuplexer which wraps inner with default settings.

Construct a new LayeredDuplexer which wraps inner. When inner reports end of stream (by returning 0), report a push but keep the stream open and continue to read data on it.

For example, when reading a file, when the reader reaches the end of the file it will report it, but consumers may wish to continue reading in case additional data is appended to the file.

Construct a new LayeredDuplexer which wraps an inner which reads its input line-by-line, such as stdin on a terminal.

Close this LayeredDuplexer and return the inner stream.

Consume this LayeredDuplexer and return the inner stream.
