Struct Reg

pub struct Reg<'a, T, A> { /* private fields */ }

A pointer to a register with volatile reads and writes.

Access permissions

The read/write permission for the register is set by the generic parameter A:

• when A is ReadOnly or ReadWrite, the register can be read from with Reg::read,
• when A is WriteOnly or ReadWrite, the register can be written to with Reg::write.

Access permissions are defined by the derive macro RegMap using the #[reg()] attribute, see Access permissions in the crate documentation.

Implementations

impl<'a, T: Integer, A: Access> Reg<'a, T, A>

pub const fn as_ptr(&self) -> *mut T

Returns a raw pointer to the underlying register.

pub fn read(&self) -> T

where A: Readable,

Perform a volatile read.

pub fn write(&self, val: T)

where A: Writable,

Perform a volatile write.

Trait Implementations

type Target = T

The target type of the pointer stored in the array.

unsafe fn from_nonnull(ptr: NonNull<Self::Target>) -> Self

Creates a new pointer to Self::Target.
