Struct Custom 

pub struct Custom { /* private fields */ }

Closure-based tick strategy for app-specific logic.

Example

use ftui_runtime::tick_strategy::{Custom, TickDecision};

let strategy = Custom::new("PriorityBased", |screen_id, tick_count, _active| {
    let divisor: u64 = match screen_id {
        "Dashboard" | "Messages" => 2,
        "Analytics" => 10,
        _ => 5,
    };
    if tick_count.is_multiple_of(divisor) {
        TickDecision::Tick
    } else {
        TickDecision::Skip
    }
});

Implementations

impl Custom

pub fn new<F>(label: impl Into<String>, f: F) -> Self

where F: Fn(&str, u64, &str) -> TickDecision + Send + 'static,

Create a custom strategy with the given label and decision function.

The closure receives (screen_id, tick_count, active_screen) and returns TickDecision::Tick or TickDecision::Skip.

Trait Implementations

impl Debug for Custom

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

Formats the value using the given formatter.

impl TickStrategy for Custom

fn should_tick( &mut self, screen_id: &str, tick_count: u64, active_screen: &str, ) -> TickDecision

Decide whether to tick an inactive screen on this frame.

fn name(&self) -> &str

Human-readable strategy name for logs/debugging.

fn debug_stats(&self) -> Vec<(String, String)>

Optional key-value debug stats.

fn on_screen_transition(&mut self, _from: &str, _to: &str)

Called when the runtime observes a screen transition.

fn maintenance_tick(&mut self, _tick_count: u64)

Called periodically for maintenance work.

fn shutdown(&mut self)

Called during clean shutdown.
