Union DevAddr 

#[repr(C)]
pub union DevAddr {
    pub raw: u32,
    pub ptr: *mut u8,
}

Device address representation.

Device address fields in the resource table are commonly filled with pointer values that aren’t known until link time. In Rust, this is only possible using actual pointer types, but the resource table pointer fields are a fixed 32 bits.

In order for this crate to be useful on 64-bit platforms, device addresses are represented using this union. It always contains a raw integer field, and on systems with 32-bit pointers, it also contains a ptr field.

Fields

raw: u32

Raw address.

ptr: *mut u8

Pointer address (only on 32-bit platforms).

Implementations

impl DevAddr

pub const fn from_u32(raw: u32) -> Self

Create a device address from a raw integer.

pub const fn const_from_ptr(ptr: *mut u8) -> Self

Create a device address from a pointer (only on 32-bit platforms).

pub fn from_ptr(ptr: *mut u8) -> Self

Create a device address from a pointer.

pub fn as_u32(&self) -> u32

Get the device address as a raw integer.

pub fn as_ptr(&self) -> *mut u8

Get the device address as a pointer.

Trait Implementations

impl Clone for DevAddr

fn clone(&self) -> DevAddr

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DevAddr

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Copy for DevAddr

impl Sync for DevAddr

Pointers are not sync, but we necessarily need pointers stored in statics.
