}

Failure to create or restrict a Mach shared-memory capability.

Variants

ZeroSize

Shared regions cannot be empty.

SizeOverflow

Requested size cannot be page-aligned.

Fields

requested: usize

Logical byte length that could not be page-aligned.

InvalidViewSize

Transition size differs from the quiescent region.

Fields

requested: usize

Requested capability view length.

region: usize

Exact page-rounded region length.

InvalidPageSize(c_int)

Kernel reported an invalid page size.

InvalidAddress(u64)

Successful allocation returned an unusable address.

NullMemoryEntry

Successful memory-entry creation returned a null capability.

UnexpectedEntrySize

Kernel changed an already aligned entry size.

Fields

expected: usize

Requested page-rounded memory-entry size.

actual: u64

Size returned by the Mach kernel.

Kernel

Mach kernel call failed.

Fields

operation: &'static str

Operation name from this bounded implementation.

code: c_int

Kernel status code.

Trait Implementations

impl Clone for MachError

fn clone(&self) -> MachError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MachError

impl Debug for MachError

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

Formats the value using the given formatter.

impl Display for MachError

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

Formats the value using the given formatter.

impl Eq for MachError

impl Error for MachError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<MachError> for MacBindingError

fn from(value: MachError) -> Self

Converts to this type from the input type.

impl PartialEq for MachError

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

Equality operator ==.

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

Inequality operator !=.
