Struct TerminfoTerminal

pub(crate) struct TerminfoTerminal<T> {
    num_colors: u32,
    out: T,
    ti: TermInfo,
}

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

A Terminal that knows how many colors it supports, with a reference to its parsed Terminfo database record.

Implementations

impl<T: Write + Send> TerminfoTerminal<T>

pub(crate) fn new_with_terminfo( out: T, terminfo: TermInfo, ) -> TerminfoTerminal<T>

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

Creates a new TerminfoTerminal with the given TermInfo and Write.

pub(crate) fn new(out: T) -> Option<TerminfoTerminal<T>>

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

Creates a new TerminfoTerminal for the current environment with the given Write.

Returns None when the terminfo cannot be found or parsed.

fn dim_if_necessary(&self, color: u32) -> u32

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

fn apply_cap(&mut self, cmd: &str, params: &[Param]) -> Result<bool>

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

Trait Implementations

impl<T: Write + Send> Terminal for TerminfoTerminal<T>

fn fg(&mut self, color: u32) -> Result<bool>

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

Sets the foreground color to the given color.

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

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

Resets all terminal attributes and colors to their defaults.

impl<T: Write> Write for TerminfoTerminal<T>

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

Writes a buffer into this writer, returning how many bytes were written.

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

Flushes this output stream, ensuring that all intermediately buffered contents reach their destination.

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.
