Struct termimad::CropWriter

pub struct CropWriter<'w, W>
where
    W: Write,
{
    pub w: &'w mut W,
    pub allowed: usize,
    pub tab_replacement: &'static str,
}

wrap a writer to ensure that at most allowed columns are written.

Fields

w: &'w mut W

allowed: usize

number of screen columns which may be covered

tab_replacement: &'static str

the string replacing a tabulation

Implementations

impl<'w, W> CropWriter<'w, W>

where W: Write,

pub fn new(w: &'w mut W, limit: usize) -> Self

pub const fn is_full(&self) -> bool

pub fn cropped_str<'a>(&self, s: &'a str) -> (Cow<'a, str>, usize)

return a tuple containing a string containing either the given &str or the part fitting the remaining width, and the width of this string)

pub fn queue_unstyled_str(&mut self, s: &str) -> Result<(), Error>

pub fn queue_str(&mut self, cs: &CompoundStyle, s: &str) -> Result<(), Error>

pub fn queue_char(&mut self, cs: &CompoundStyle, c: char) -> Result<(), Error>

pub fn queue_unstyled_char(&mut self, c: char) -> Result<(), Error>

pub fn queue_unstyled_g_string(&mut self, s: String) -> Result<(), Error>

a “g_string” is a “gentle” one: each char takes one column on screen. This function must thus not be used for unknown strings.

pub fn queue_g_string( &mut self, cs: &CompoundStyle, s: String ) -> Result<(), Error>

a “g_string” is a “gentle” one: each char takes one column on screen. This function must thus not be used for unknown strings.
