Struct vt100::Parser

pub struct Parser { /* fields omitted */ }

A parser for terminal output which produces an in-memory representation of the terminal contents.

Implementations

impl Parser

pub fn new(rows: u16, cols: u16, scrollback_len: usize) -> Self

Creates a new terminal parser of the given size and with the given amount of scrollback.

pub fn process(&mut self, bytes: &[u8])

Processes the contents of the given byte string, and updates the in-memory terminal state.

pub fn set_size(&mut self, rows: u16, cols: u16)

Resizes the terminal.

pub fn set_scrollback(&mut self, rows: usize)

Scrolls to the given position in the scrollback.

This position indicates the offset from the top of the screen, and should be 0 to put the normal screen in view.

This affects the return values of methods called on parser.screen(): for instance, parser.screen().cell(0, 0) will return the top left corner of the screen after taking the scrollback offset into account. It does not affect parser.process() at all.

The value given will be clamped to the actual size of the scrollback.

pub fn screen(&self) -> &Screen

Returns a reference to a Screen object containing the terminal state.

Trait Implementations

impl Default for Parser

fn default() -> Self

Returns a parser with dimensions 80x24 and no scrollback.

impl Write for Parser

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

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

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

Flush 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, fmt: Arguments<'_>) -> Result<(), Error>

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

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

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