Struct term::Terminal
pub struct Terminal<T> {
// some fields omitted
}A Terminal that knows how many colors it supports, with a reference to its parsed TermInfo database record.
Methods
impl<T: Writer> Terminal<T>
fn new(out: T) -> Result<Terminal<T>, ~str>
Returns a wrapped output stream (Terminal<T>) as a Result.
Returns Err() if the TERM environment variable is undefined.
TERM should be set to something like xterm-color or screen-256color.
Returns Err() on failure to open the terminfo database correctly.
Also, in the event that the individual terminfo database entry can not
be parsed.
fn fg(&mut self, color: Color) -> IoResult<bool>
Sets the foreground color to the given color.
If the color is a bright color, but the terminal only supports 8 colors, the corresponding normal color will be used instead.
Returns Ok(true) if the color was set, Ok(false) otherwise, and Err(e)
if there was an I/O error.
fn bg(&mut self, color: Color) -> IoResult<bool>
Sets the background color to the given color.
If the color is a bright color, but the terminal only supports 8 colors, the corresponding normal color will be used instead.
Returns Ok(true) if the color was set, Ok(false) otherwise, and Err(e)
if there was an I/O error.
fn attr(&mut self, attr: Attr) -> IoResult<bool>
Sets the given terminal attribute, if supported.
Returns Ok(true) if the attribute was supported, Ok(false) otherwise,
and Err(e) if there was an I/O error.
fn supports_attr(&self, attr: Attr) -> bool
Returns whether the given terminal attribute is supported.
fn reset(&mut self) -> IoResult<()>
Resets all terminal attributes and color to the default.
Returns Ok().
fn unwrap(self) -> T
Returns the contained stream
fn get_ref<'a>(&'a self) -> &'a T
Gets an immutable reference to the stream inside
fn get_mut<'a>(&'a mut self) -> &'a mut T
Gets a mutable reference to the stream inside
