Trait OngoingScrollExt 

pub trait OngoingScrollExt {
    // Required method
    fn lock_axis(&mut self, delta: &mut Point<Pixels>, touch_phase: TouchPhase);
}

gpui delimits scroll gestures with std::time::Instant, which is unimplemented on wasm32: the first wheel event over an axis-locked scroll area panics with “time not implemented on this platform” and takes the whole application down, leaving the canvas unresponsive. Losing the axis lock in the browser is by far the lesser cost, so the locks below are no-ops there.

Required Methods

fn lock_axis(&mut self, delta: &mut Point<Pixels>, touch_phase: TouchPhase)

Locks a wheel delta to the axis its gesture started on, where the platform supports it.

Dyn Compatibility

This trait is dyn compatible.

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