Enum moving_gc_arena::Error

pub enum Error {
    Indeterminable,
    IncorrectRegion,
    EntryExpired,
    UnexpectedInternalState,
}

Type of region access errors.

This does not implement std::Error, which is not available for a no_std crate

Variants

Indeterminable

Incorrect usage resulted in an error, but the system does not have enough data to determine exactly what the error was.

Enabling the feature “debug-arena” will allow the library to have appropriate data in most cases, with high costs to space usage.

IncorrectRegion

This index has been used with a region for which it was not created.

EntryExpired

This index has been invalidated by a garbage collection.

UnexpectedInternalState

This library is in an unexpected internal state.

The only way that this is expected to occur for user code is in the case of a non-compliant function for deep cloning methods, which rely on complex invariants to return to a normal region state.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl PartialEq<Error> for Error

fn eq(&self, other: &Error) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
