Enum SlotError 

#[non_exhaustive]
pub enum SlotError {
    Exhausted,
    IntId(IntIdError),
}

Errors from the slot allocator.

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.

Exhausted

All 32 slots are taken; the per-class API caps prevent this for valid configurations.

IntId(IntIdError)

IntId derivation failed; should be impossible for slot < 32 but surfaces the error rather than panicking.

Trait Implementations

impl Debug for SlotError

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

Formats the value using the given formatter.

impl Display for SlotError

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

Formats the value using the given formatter.

impl Error for SlotError

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.

impl From<IntIdError> for SlotError

fn from(source: IntIdError) -> Self

Converts to this type from the input type.
