Struct Number 

pub struct Number {
    pub min: Option<f64>,
    pub max: Option<f64>,
    pub step: Option<f64>,
    pub decimals: Option<usize>,
    pub unit: Option<String>,
}

Available on crate feature property-grid only.

The limits and look of a number property.

Fields

min: Option<f64>

max: Option<f64>

step: Option<f64>

How far Up and Down move the value while it is edited. A whole step also makes values between steps invalid.

decimals: Option<usize>

Decimal places shown. Defaults to those of the step, or as many as the value needs.

unit: Option<String>

Shown after the value, such as px or %, and accepted when typed.

Implementations

impl Number

pub fn precision(&self) -> Option<usize>

The decimal places values are shown with, if fixed.

pub fn format(&self, value: f64) -> String

The value as text, without the unit.

pub fn display(&self, value: f64) -> String

The value as text, with the unit.

pub fn parse(&self, input: &str) -> Result<f64, String>

Reads typed text, with or without the unit, and checks it.

pub fn check(&self, value: f64) -> Result<f64, String>

Checks a value against the limits and a whole step.

pub fn stepped(&self, value: f64, up: bool) -> f64

The value one step up or down, kept within the limits.

Trait Implementations

impl Clone for Number

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Number

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

Formats the value using the given formatter.

impl Default for Number

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Number

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

Equality operator ==.

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

Inequality operator !=.
