Struct ParamSpec 

pub struct ParamSpec {
    pub name: Cow<'static, str>,
    pub default: Option<f32>,
    pub admitted: RangeInclusive<f32>,
    pub usable: RangeInclusive<f32>,
}

A parameter a painter set takes from the theme document: its name, the value it has when a document leaves it out (None: a document must state it), the band a document may state it in, and the band the theme is built at.

Fields

name: Cow<'static, str>

default: Option<f32>

admitted: RangeInclusive<f32>

usable: RangeInclusive<f32>

Implementations

impl ParamSpec

pub fn new( name: &'static str, default: Option<f32>, band: RangeInclusive<f32>, ) -> ParamSpec

name, admitted and usable across band; default when left out.

pub fn usable_within(self, usable: RangeInclusive<f32>) -> ParamSpec

This parameter, built at no more than usable of its admitted band.

Trait Implementations

impl Clone for ParamSpec

fn clone(&self) -> ParamSpec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ParamSpec

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for ParamSpec

fn eq(&self, other: &ParamSpec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
