Expand description

Common Timeline knobs shared by every animation type (duration, repeat, auto-reverse, …). Implemented through the object’s raw Timeline*.

Required Methods§

Source

fn timeline_raw(&self) -> *mut c_void

Borrowed Noesis::Timeline* for self.

Provided Methods§

Source

fn set_duration_secs(&mut self, seconds: f64) -> bool

Set the single-pass duration in seconds.

Source

fn set_duration_auto(&mut self) -> bool

Set Duration="Automatic" (resolved from the content, e.g. key frames).

Source

fn set_duration_forever(&mut self) -> bool

Set Duration="Forever".

Source

fn duration_secs(&self) -> Option<f64>

Read the configured single-pass duration in seconds, or None if the duration is Automatic / Forever (not a resolved TimeSpan).

Source

fn set_begin_time_secs(&mut self, seconds: f64) -> bool

Delay before the timeline begins, in seconds.

Source

fn set_auto_reverse(&mut self, value: bool) -> bool

Play forwards then backwards each iteration when true.

Source

fn set_speed_ratio(&mut self, value: f32) -> bool

Rate at which time progresses relative to the parent (default 1.0).

Source

fn set_fill_behavior(&mut self, behavior: FillBehavior) -> bool

Behaviour once the active period ends (hold the end value or release it).

Source

fn set_repeat_count(&mut self, count: f32) -> bool

Repeat a fixed number of (possibly fractional) iterations.

Source

fn set_repeat_duration_secs(&mut self, seconds: f64) -> bool

Repeat for a fixed wall-clock duration, in seconds.

Source

fn set_repeat_forever(&mut self) -> bool

Repeat forever.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
