Specific error kinds reported by the eBPF verifier.

Each variant maps to an errno that matches the one returned by the Linux verifier for the equivalent failure, see VerifierErrorKind::errno.

Implementations

impl VerifierErrorKind

pub fn errno(&self) -> u32

The Linux errno corresponding to this error.

Trait Implementations

impl Clone for VerifierErrorKind

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for VerifierErrorKind

impl Debug for VerifierErrorKind

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

impl Eq for VerifierErrorKind

impl Error for VerifierErrorKind

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

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

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

impl PartialEq for VerifierErrorKind

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

Equality operator ==.

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

Inequality operator !=.
