Trait ReservationSet 

pub trait ReservationSet<Reg>
where
    Reg: Register,
{
    // Required methods
    fn reservation(&self) -> Option<Reg::Type>;
    fn set_reservation(&mut self, address: Reg::Type);
    fn clear_reservation(&mut self);
}

Reservation set used to implement Zalrsc extension’s lr/sc instruction pairs.

lr places a reservation on an address, and a subsequent sc succeeds only if the reservation is still held for the same address. Regardless of success or failure, executing sc always invalidates the reservation, as does a subsequent lr.

Required Methods

fn reservation(&self) -> Option<Reg::Type>

Returns the address of the currently held reservation, if any

fn set_reservation(&mut self, address: Reg::Type)

Place a reservation on address, replacing any previously held reservation

fn clear_reservation(&mut self)

Clear any currently held reservation

Dyn Compatibility

This trait is dyn compatible.

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