Implementations§
source§impl Segment
impl Segment
pub fn new(start: &Coordinate, end: &Coordinate) -> Self
Methods from Deref<Target = Line<f64>>§
sourcepub fn dx(&self) -> T
pub fn dx(&self) -> T
Calculate the difference in ‘x’ components (Δx).
Equivalent to:
line.end.x - line.start.x
sourcepub fn dy(&self) -> T
pub fn dy(&self) -> T
Calculate the difference in ‘y’ components (Δy).
Equivalent to:
line.end.y - line.start.y
sourcepub fn slope(&self) -> T
pub fn slope(&self) -> T
Calculate the slope (Δy/Δx).
Equivalent to:
line.dy() / line.dx()
Note that:
Line::new(a, b).slope() == Line::new(b, a).slope()
sourcepub fn determinant(&self) -> T
pub fn determinant(&self) -> T
Calculate the determinant of the line.
Equivalent to:
line.start.x * line.end.y - line.start.y * line.end.x
Note that:
Line::new(a, b).determinant() == -Line::new(b, a).determinant()
pub fn start_point(&self) -> Point<T>
pub fn end_point(&self) -> Point<T>
pub fn points(&self) -> (Point<T>, Point<T>)

source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self
with the foreground set to
value
.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red()
and
green()
, which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg()
:
use yansi::{Paint, Color};
painted.fg(Color::White);
Set foreground color to white using white()
.
use yansi::Paint;
painted.white();
source§fn bright_black(&self) -> Painted<&T>
fn bright_black(&self) -> Painted<&T>

set to

source§fn bright_red(&self) -> Painted<&T>
fn bright_red(&self) -> Painted<&T>
source§fn bright_green(&self) -> Painted<&T>

§Example
println!("{}", value.bright_green());
source§fn bright_yellow(&self) -> Painted<&T>
fn bright_yellow(&self) -> Painted<&T>
Returns self
with the

set to
Color::BrightYellow

source§fn bright_magenta(&self) -> Painted<&T>
fn bright_magenta(&self) -> Painted<&T>
Returns self

fg()
set to
Color::BrightMagenta
.
§Example
println!("{}", value.bright_magenta());
source§fn bright_cyan(&self) -> Painted<&T>
fn bright_cyan(&self) -> Painted<&T>
source§fn bright_white(&self) -> Painted<&T>
fn bright_white(&self) -> Painted<&T>
Returns self
with the
fg()
set to
Color::BrightWhite
.
§Example
println!("{}", value.bright_white());
source§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self
with the background set to
value
.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red()
and
on_green()
, which have the same functionality but
are pithier.
§Example
Set background color to red using fg()
:
use yansi::{Paint, Color};
painted.bg(Color::Red);
Set background color to red using on_red()
.
use yansi::Paint;
painted.on_red();

fn on_bright_red(&self) -> Painted<&T>
source§fn on_bright_green(&self) -> Painted<&T>

source§fn on_bright_yellow(&self) -> Painted<&T>
fn on_bright_yellow(&self) -> Painted<&T>

source§fn on_bright_blue(&self) -> Painted<&T>
fn on_bright_blue(&self) -> Painted<&T>

bg()
set to
Color::BrightBlue
.
§Example
println!("{}", value.on_bright_blue());
source§fn on_bright_magenta(&self) -> Painted<&T>
fn on_bright_magenta(&self) -> Painted<&T>
Returns self

.
§Example
println!("{}", value.on_bright_magenta());
source§fn on_bright_cyan(&self) -> Painted<&T>
fn on_bright_cyan(&self) -> Painted<&T>
Returns self
with the
bg()
set to
Color::BrightCyan
.
§Example
println!("{}", value.on_bright_cyan());
source§fn on_bright_white(&self) -> Painted<&T>
fn on_bright_white(&self) -> Painted<&T>
Returns self
with the
bg()
set to

.
§Example
println!("{}", value.on_bright_white());
source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute
value
.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold()
and
underline()
, which have the same functionality
but are pithier.
§Example
Make text bold using attr()
:
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);
Make text bold using using bold()
.
use yansi::Paint;
painted.bold();
source§fn underline(&self) -> Painted<&T>

with the
attr()
set to
Attribute::Underline

source§fn rapid_blink(&self) -> Painted<&T>

source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi
Quirk
value
.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask()
and
wrap()
, which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk()
:
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);
Enable wrapping using wrap()
.
use yansi::Paint;
painted.wrap();
source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition
value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted
only when both stdout
and stderr
are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
