Enum ZoomStep 

pub enum ZoomStep {
    In,
    Out,
    Reset,
}

What a zoom gesture asks for, and what the window’s Zoom in, Zoom out and Actual size actions carry.

Variants

In

One level larger (Ctrl+Plus, scroll up, pinch out).

Out

One level smaller (Ctrl+Minus, scroll down, pinch in).

Reset

Back to the default size (Ctrl+0).

Implementations

impl ZoomStep

pub fn apply(self, current: f32) -> f32

The factor one step from current, between the toolkit’s LEVELS, or ZoomModel::default_factor for Self::Reset.

pub fn apply_in(self, levels: &[f32], reset: f32, current: f32) -> f32

The factor one step from current, between levels (ascending) and back to reset for Self::Reset: the rule every app’s own scale follows, whatever its levels are.

pub fn from_key( conventions: PlatformConventions, modifiers: ModifiersState, key: &Key, ) -> Option<ZoomStep>

The step a pressed key means: the platform’s command modifier with + (or =, its unshifted key on many layouts), - or 0, from the main row or the keypad. Alt keeps its own meaning.

Trait Implementations

impl Clone for ZoomStep

fn clone(&self) -> ZoomStep

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ZoomStep

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ZoomStep

fn deserialize<__D>( __deserializer: __D, ) -> Result<ZoomStep, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ZoomStep

fn eq(&self, other: &ZoomStep) -> 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.

impl Serialize for ZoomStep

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
