Struct r3::kernel::cfg::CfgInterruptHandlerBuilder

pub struct CfgInterruptHandlerBuilder<System> { /* fields omitted */ }

Configuration builder type for InterruptHandler.

Implementations

impl<System: Port> CfgInterruptHandlerBuilder<System>

pub const fn start(self, start: fn(_: usize)) -> Self

[Required] Specify the entry point.

pub const fn param(self, param: usize) -> Self

Specify the parameter to start. Defaults to 0.

pub const fn line(self, line: InterruptNum) -> Self

[Required] Specify the interrupt line to attach the interrupt handler to.

pub const fn priority(self, priority: i32) -> Self

Specify the priority. Defaults to 0 when unspecified.

When multiple handlers are registered to a single interrupt line, those with smaller priority values will execute earlier.

This should not be confused with an interrupt line’s priority.

pub const unsafe fn unmanaged(self) -> Self

Indicate that the entry point function is unmanaged-safe (designed to execute as an unmanaged interrupt handler).

If an interrupt line is not configured with an initial priority value that falls within a managed range, configuration will fail unless all of its attached interrupt handlers are marked as unmanaged-safe.

Safety

The behavior of system calls is undefined in an unmanaged interrupt handler.

pub const fn finish(
    self,
    cfg: &mut CfgBuilder<System>
) -> InterruptHandler<System>

Complete the registration of an interrupt handler, returning an InterruptHandler object.
