Struct ResourceSize 

pub struct ResourceSize(/* private fields */);

Resource size type.

This wraps either u32 or u64 depending on the config option CONFIG_PHYS_ADDR_T_64BIT, and it can be a u64 even on 32-bit architectures.

Examples

use kernel::io::ResourceSize;

let size = ResourceSize::from_raw(0x1000);
assert_eq!(size.into_raw(), 0x1000);

// Round-trips through the raw C type.
let raw: kernel::bindings::resource_size_t = size.into();
assert_eq!(ResourceSize::from(raw), size);

// Fallible conversion to `usize` (can truncate on 32-bit).
assert_eq!(usize::try_from(size)?, 0x1000);

Implementations

impl ResourceSize

pub const fn from_raw(value: resource_size_t) -> Self

Creates a resource size from the raw C type.

pub const fn into_raw(self) -> resource_size_t

Turns this resource size into the raw C type.
