Struct BufStream 

pub struct BufStream { /* private fields */ }

A Stream that records writes and style changes.

Implementations

impl BufStream

pub fn new() -> BufStream

Create a new, empty BufStream.

pub fn playback(&self, other: &mut dyn Stream) -> Result<()>

Perform the actions recorded on this BufStream onto another Stream.

Trait Implementations

impl Default for BufStream

fn default() -> BufStream

Returns the “default value” for a type.

impl Stream for BufStream

The Stream methods of this implementation always succeed with Ok(()).

fn reset(&mut self) -> Result<()>

Record the call to reset.

fn fg(&mut self, fg: Color) -> Result<()>

Record the call to fg.

fn em(&mut self) -> Result<()>

Record the call to em.

fn is_cli(&self) -> bool

Always false.

impl Write for BufStream

fn write(&mut self, data: &[u8]) -> Result<usize>

Record the call to write.

fn flush(&mut self) -> Result<()>

Record the call to flush.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
