Struct kernel::syscall::validation::UserSlice

pub struct UserSlice<'a, T> {
    ptr: *mut T,
    length: usize,
    _phantom: PhantomData<&'a ()>,
}

Represents a slice of Ts in userspace.

Fields

ptr: *mut T

length: usize

_phantom: PhantomData<&'a ()>

Implementations

impl<'a, T> UserSlice<'a, T>

pub fn new(ptr: *mut T, length: usize) -> UserSlice<'a, T>

pub fn validate_read(&self) -> Result<&'a [T], ()>

pub fn validate_write(&mut self) -> Result<&'a mut [T], ()>

Validate this slice for a write, BUT DOES NOT ACTUALLY WRITE ANYTHING INTO IT. You must write into the returned mutable reference, generally using either copy_from_slice if T: Copy, or clone_from_slice otherwise.
