pub struct Percentage {
    value: CSSFloat,
    calc_clamping_mode: Option<AllowedNumericType>,
}
Expand description

A percentage value.

Fields§

§value: CSSFloat

The percentage value as a float.

[0 .. 100%] maps to [0.0 .. 1.0]

§calc_clamping_mode: Option<AllowedNumericType>

If this percentage came from a calc() expression, this tells how clamping should be done on the value.

Implementations§

source§

impl Percentage

source

pub(super) fn new_with_clamping_mode( value: CSSFloat, calc_clamping_mode: Option<AllowedNumericType> ) -> Self

Creates a percentage from a numeric value.

source

pub fn new(value: CSSFloat) -> Self

Creates a percentage from a numeric value.

source

pub fn zero() -> Self

0%

source

pub fn hundred() -> Self

100%

source

pub fn get(&self) -> CSSFloat

Gets the underlying value for this float.

source

pub fn to_number(&self) -> Number

Returns this percentage as a number.

source

pub fn calc_clamping_mode(&self) -> Option<AllowedNumericType>

Returns the calc() clamping mode for this percentage.

source

pub fn reverse(&mut self)

Reverses this percentage, preserving calc-ness.

For example: If it was 20%, convert it into 80%.

source

pub fn parse_with_clamping_mode<'i, 't>( context: &ParserContext<'_>, input: &mut Parser<'i, 't>, num_context: AllowedNumericType ) -> Result<Self, ParseError<'i>>

Parses a specific kind of percentage.

source

pub fn parse_non_negative<'i, 't>( context: &ParserContext<'_>, input: &mut Parser<'i, 't> ) -> Result<Self, ParseError<'i>>

Parses a percentage token, but rejects it if it’s negative.

source

pub fn parse_zero_to_a_hundred<'i, 't>( context: &ParserContext<'_>, input: &mut Parser<'i, 't> ) -> Result<Self, ParseError<'i>>

Parses a percentage token, but rejects it if it’s negative or more than 100%.

source

pub fn clamp_to_hundred(self) -> Self

Clamp to 100% if the value is over 100%.
