Struct OpError 

pub struct OpError {
    pub kind: OpErrorKind,
    pub reason: &'static str,
    pub detail: String,
}

Op invocation failure detail. Surfaced by the engine when dispatch_atomic returns Err or the dispatch table lookup misses. Three-field shape: kind is a stable categorical label, reason is a &'static str (e.g. "blocklisted", "cooldown") callers can match on, detail is a free-form human-readable description.

Fields

kind: OpErrorKind

Categorical kind. Default Other.

reason: &'static str

Stable diagnostic label (e.g. "blocklisted", "cooldown", "nak") consumers match on. Default "".

detail: String

Human-readable failure detail.

Trait Implementations

impl Clone for OpError

fn clone(&self) -> OpError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OpError

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

Formats the value using the given formatter.

impl Default for OpError

fn default() -> OpError

Returns the “default value” for a type.

impl Display for OpError

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

Formats the value using the given formatter.

impl Error for OpError

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.
