Enum OperationMetadataError 

pub enum OperationMetadataError {
    ReadOnlyMustBeSafe,
    StateChangeCannotBeSafe,
    NonIdempotentRetry,
}

Incoherent operation metadata.

Variants

ReadOnlyMustBeSafe

Read-only operations must use safe request semantics.

StateChangeCannotBeSafe

Mutating and destructive operations cannot use safe semantics.

NonIdempotentRetry

Non-idempotent operations cannot be retry eligible.

impl Eq for OperationMetadataError

impl Error for OperationMetadataError

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
