Enum MulticodecOperationError 

#[non_exhaustive]
pub enum MulticodecOperationError {
    UnknownName,
    InvalidPrefix,
    RegistryInvariant,
    AllocationFailure,
}

Semantic failure reasons for multicodec lookup operations.

The display strings are fixed and do not include caller input. Boundary adapters map these reasons into their public typed error contracts.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

UnknownName

The requested name is not present in the supported registry.

InvalidPrefix

The input does not start with a supported multicodec prefix.

RegistryInvariant

Primitive registry metadata violated an executor invariant.

AllocationFailure

The bounded semantic result could not reserve its required storage.

impl Eq for MulticodecOperationError

impl Error for MulticodecOperationError

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
