Trait ScanExecutor 

pub trait ScanExecutor:
    Send
    + Sync
    + 'static {
    // Required method
    fn spawn_blocking(&self, job: ScanJob) -> ScanFuture;
}

A pluggable executor for blocking scan_dir calls.

Applications that already manage a blocking-task pool can implement this to route tree expansions through it instead of spinning up a new std::thread per scan.

Implementors should ensure the returned future resolves once the job has actually run — cancelling or losing the job will leave the widget stuck in “loading” forever (is_loaded never flips to true for the affected directory).

The widget holds the executor behind an Arc, so an impl that owns any shared state should wrap it in an Arc internally or store only Send + Sync references.

Required Methods

fn spawn_blocking(&self, job: ScanJob) -> ScanFuture

Run job on a blocking-capable worker and return a future that resolves to its result.

The future is driven from the iced runtime. It must be Send + 'static — iced spawns tasks across threads.
