Enum kernel::process::Error

pub enum Error {
    NoSuchApp,
    OutOfMemory,
    AddressOutOfBounds,
    InactiveApp,
    KernelError,
    AlreadyInUse,
}

Error types related to processes.

Variants

NoSuchApp

The process has been removed and no longer exists. For example, the kernel could stop a process and re-claim its resources.

OutOfMemory

The process does not have enough memory to complete the requested operation.

AddressOutOfBounds

The provided memory address is not accessible or not valid for the process.

InactiveApp

The process is inactive (likely in a fault or exit state) and the attempted operation is therefore invalid.

KernelError

This likely indicates a bug in the kernel and that some state is inconsistent in the kernel.

AlreadyInUse

Indicates some process data, such as a Grant, is already borrowed.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl From<Error> for CommandReturn

fn from(perr: Error) -> Self

Converts to this type from the input type.

impl From<Error> for ErrorCode

fn from(err: Error) -> ErrorCode

Converts to this type from the input type.

impl From<Error> for Result<(), ErrorCode>

fn from(err: Error) -> Result<(), ErrorCode>

Converts to this type from the input type.

impl PartialEq for Error

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

This method tests for self and other values to be equal, and is used by ==.

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

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