InvalidResult(String)

Hook returned invalid result data.

AutoDisabled

Hook was auto-disabled after too many consecutive failures.

Fields

name: String

consecutive_traps: u32

InvalidHookPoint(String)

Hook point not found or invalid.

IoError(Error)

I/O error loading a WASM module.

AbiVersionMismatch

WASM module was compiled against an incompatible ABI version.

Fields

hook_name: String

expected: i32

found: Option<i32>

Trait Implementations

impl Debug for HookError

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

Formats the value using the given formatter.

impl Display for HookError

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

Formats the value using the given formatter.

impl Error for HookError

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<Error> for HookError

fn from(e: Error) -> Self

Converts to this type from the input type.
