RelativeRegisterLoc

kernel::io::register

Struct RelativeRegisterLoc 

Source 
pub struct RelativeRegisterLoc<T: WithBase, B: ?Sized>(/* private fields */);
Expand description

Location of a relative register.

This can either be an immediately accessible regular RelativeRegister, or a RelativeRegisterArray that needs one additional resolution through RelativeRegisterLoc::at.

Implementations§

Source§

impl<T, B> RelativeRegisterLoc<T, B>
where T: Register + WithBase, B: RegisterBase<T::BaseFamily> + ?Sized,

Source

pub const fn new() -> Self

Returns the location of a relative register or register array.

Source§

impl<T, B> RelativeRegisterLoc<T, B>
where T: RelativeRegisterArray, B: RegisterBase<T::BaseFamily> + ?Sized,

Methods exclusive to RelativeRegisterLocs created with a RelativeRegisterArray.

Source

pub fn at(self, idx: usize) -> RelativeRegisterArrayLoc<T, B>

Returns the location of the register at position idx, with build-time validation.

Source

pub fn try_at(self, idx: usize) -> Option<RelativeRegisterArrayLoc<T, B>>

Returns the location of the register at position idx, with runtime validation.
