}Expand description
RoundingStrategy represents the different rounding strategies that can be used by
round_dp_with_strategy.
Variants§
MidpointNearestEven
When a number is halfway between two others, it is rounded toward the nearest even number. Also known as “Bankers Rounding”. e.g. 6.5 -> 6, 7.5 -> 8
MidpointAwayFromZero
When a number is halfway between two others, it is rounded toward the nearest number that is away from zero. e.g. 6.4 -> 6, 6.5 -> 7, -6.5 -> -7
MidpointTowardZero
When a number is halfway between two others, it is rounded toward the nearest number that is toward zero. e.g. 6.4 -> 6, 6.5 -> 6, -6.5 -> -6
ToZero
The number is always rounded toward zero. e.g. -6.8 -> -6, 6.8 -> 6
AwayFromZero
The number is always rounded away from zero. e.g. -6.8 -> -7, 6.8 -> 7
ToNegativeInfinity
The number is always rounded towards negative infinity. e.g. 6.8 -> 6, -6.8 -> -7
ToPositiveInfinity
The number is always rounded towards positive infinity. e.g. 6.8 -> 7, -6.8 -> -6
BankersRounding
When a number is halfway between two others, it is rounded toward the nearest even number. e.g. 6.5 -> 6, 7.5 -> 8
RoundHalfUp
Rounds up if the value >= 5, otherwise rounds down, e.g. 6.5 -> 7
RoundHalfDown
Rounds down if the value =< 5, otherwise rounds up, e.g. 6.5 -> 6, 6.51 -> 7 1.4999999 -> 1
RoundDown
Always round down.
RoundUp
Always round up.

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>

set to

§Example

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().

bg()
set to
Color::BrightWhite.
§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>

attr()
set to
Attribute::RapidBlink.
§Example
println!("{}", value.rapid_blink());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 clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.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);
