Struct Region 

pub struct Region { /* private fields */ }

A contiguous region of memory addressed by offset.

Safety

The caller must ensure:

• base is valid for len bytes and properly aligned for all contained types
• the memory remains valid for the lifetime of this Region

Implementations

impl Region

pub unsafe fn from_raw(base: *mut u8, len: usize) -> Self

Create a region from a raw pointer and length.

Safety

• base must be valid for len bytes
• base must be aligned for all contained types
• the memory must remain valid for the lifetime of this Region

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

Returns the base pointer of the region.

pub fn len(&self) -> usize

Returns the size of the region in bytes.

pub fn is_empty(&self) -> bool

Returns true if the region has zero length.

pub fn offset(&self, off: usize) -> *mut u8

Returns a pointer to offset off within the region.

pub unsafe fn get<T>(&self, off: usize) -> &T

Returns a reference to a T at the given byte offset.

Safety

The offset must be aligned for T and within bounds.

pub unsafe fn get_mut<T>(&self, off: usize) -> &mut T

Returns a mutable reference to a T at the given byte offset.

Safety

The offset must be aligned for T and within bounds.
