Trait Enable 

pub trait Enable {
    // Required methods
    fn enabled(&self) -> bool;
    async fn changed(&mut self);
}

Whether the receiver should be running, and a way to wait for that to change.

Separate from Power because the two have different owners: the answer comes from PROP_GNSS_ENABLED by way of the device-domain mirror, while the sequencing belongs to the board.

Required Methods

fn enabled(&self) -> bool

Whether the receiver is wanted right now.

async fn changed(&mut self)

Complete when the answer changes.

Must be cancellation-safe. The pump drops and re-creates this future every time a byte arrives, so an implementation that loses a change it was cancelled on would leave the receiver powered after it was switched off. An embassy_sync::watch::Watch receiver behaves correctly; a bare Signal does not.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
