Expand description

Error codes returned by VeridianOS system calls.

Variants§

InvalidArgument

One or more arguments are invalid.

PermissionDenied

Caller lacks the required capability or permission.

NotFound

The requested resource was not found.

OutOfMemory

Insufficient memory to complete the operation.

AlreadyExists

The resource already exists.

Timeout

The operation timed out.

WouldBlock

The operation would block and non-blocking mode was requested.

NotSupported

The operation is not supported on this object.

NotImplemented

The system call is not yet implemented.

IoError

An I/O error occurred.

BadDescriptor

The file descriptor or handle is invalid.

BufferTooSmall

The buffer provided is too small.

InternalError

An internal kernel error occurred.

Trait Implementations§

impl Clone for SyscallError

fn clone(&self) -> SyscallError

Returns a duplicate of the value. Read more

1.0.0§

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

Performs copy-assignment from source. Read more

impl Debug for SyscallError

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

Formats the value using the given formatter. Read more

impl Display for SyscallError

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

Formats the value using the given formatter. Read more

impl PartialEq for SyscallError

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

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

1.0.0§

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

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