Enum KernelError 

pub enum KernelError {
    CapNotFound(CapId),
    CapIdExhausted,
    CapIdCollision(CapId),
    InvalidCapability(String),
    CounterOverflow(&'static str),
}

Error type for kernel operations

Variants

CapNotFound(CapId)

Capability not found in the table

CapIdExhausted

Capability ID exhausted (overflow)

CapIdCollision(CapId)

Capability ID collision during insert

InvalidCapability(String)

Invalid capability state

CounterOverflow(&'static str)

Counter overflow (time or epoch would exceed u64::MAX)

Trait Implementations

impl Clone for KernelError

fn clone(&self) -> KernelError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KernelError

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

Formats the value using the given formatter.

impl Display for KernelError

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

Formats the value using the given formatter.

impl Error for KernelError

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<KernelError> for Error

fn from(e: KernelError) -> Self

Converts to this type from the input type.

impl PartialEq for KernelError

fn eq(&self, other: &KernelError) -> 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.
