pub struct Key<T> {
    pub d: Desc,
    /* private fields */
}

Fields

d: Desc

Implementations

impl Key<bool>

pub const fn bool(name: &'static str, def: bool) -> Key<bool>

impl Key<i64>

pub const fn int(name: &'static str, def: i64, min: i64, max: i64) -> Key<i64>

a whole number in min..=max (step 1)

pub const fn step(self, step: i64) -> Key<i64>

the step of the number box’s arrows and arrow keys

impl Key<f64>

pub const fn num( name: &'static str, def: f64, min: f64, max: f64, dec: u32, ) -> Key<f64>

a number in min..=max, shown with dec decimals

impl Key<String>

pub const fn text( name: &'static str, def: &'static str, max: usize, ) -> Key<String>

pub const fn help(self, help: &'static str) -> Key<T>

a line of explanation below the label

pub const fn hidden(self) -> Key<T>

not on the settings page (state the app keeps)

pub const fn restart(self) -> Key<T>

takes effect after a restart
