MemoryDeclarationError

Failure to construct a complete allocation declaration snapshot.

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.

TooManyDeclarations

DuplicateRequest

Fields

stable_key: StableKey

Declaration(DeclarationSnapshotError)

Declaration validation failed.

InvalidAuthority

External registration attempted to use an invalid authority identifier.

Fields

reason: &'static str

Validation failure.

ReservedAuthority

External registration attempted to impersonate the internal authority.

Fields

authority: String

Reserved authority identifier.

ReservedStableKey

External registration attempted to claim the internal stable-key namespace.

Fields

stable_key: String

Reserved stable key.

Trait Implementations

impl Eq for MemoryDeclarationError

impl Error for MemoryDeclarationError

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
