Enum PinUpdateError

pub enum PinUpdateError {
    UnexpectedNumberOfDescendants(u64, u64),
    NotPinnedRecursive,
    AlreadyPinnedRecursive,
    CannotUnpinUnpinned,
    CannotUnpinDirectOnRecursivelyPinned,
}

Describes the error variants for updates to object pinning.

Variants

UnexpectedNumberOfDescendants(u64, u64)

The current and expected descendants of an already recursively pinned object don’t match.

NotPinnedRecursive

Recursive update fails as it wasn’t pinned recursively.

AlreadyPinnedRecursive

Not allowed: Adding direct pin while pinned recursive.

CannotUnpinUnpinned

Can’t unpin already inpinned.

CannotUnpinDirectOnRecursivelyPinned

Can’t unpin direct on a recursively pinned object.

Trait Implementations

impl Debug for PinUpdateError

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

Formats the value using the given formatter.

impl Display for PinUpdateError

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

Formats the value using the given formatter.

impl Error for PinUpdateError

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.
