Enum UserSliceError 

pub enum UserSliceError {
    NullPointer,
    KernelAddress,
    Overflow,
    TooLong,
    NotMapped,
    PermissionDenied,
    InvalidSize,
}

Errors that can occur when constructing or using a UserSlice.

Variants

NullPointer

The pointer is null.

KernelAddress

The region extends into or past kernel address space.

Overflow

base + len overflows (wraps around the address space).

TooLong

The region exceeds the maximum allowed length.

NotMapped

One or more pages in the region are not mapped.

PermissionDenied

The mapping lacks the required permission (e.g. not writable).

InvalidSize

The slice is too small for the requested operation.

Trait Implementations

impl Clone for UserSliceError

fn clone(&self) -> UserSliceError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UserSliceError

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

Formats the value using the given formatter.

impl From<UserSliceError> for SyscallError

fn from(e: UserSliceError) -> Self

Performs the from operation.

impl PartialEq for UserSliceError

fn eq(&self, other: &UserSliceError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
