Enum Error

pub enum Error {
    InvalidId,
    FromIdFailed,
    ToIdFailed,
    IdOverflow,
}

Errors that may occur when using an ArenaSet. ArenaSet: struct.ArenaSet.html

Variants

InvalidId

The ID does not represent an interned item. This could mean either that the ID has never been returned from a call to intern; or was subsequently passed to disintern.

FromIdFailed

Could not convert an ID type to a Vec index.

ToIdFailed

Could not convert a Vec index to an ID type.

IdOverflow

The ID type cannot uniquely represent any more items.

For instance, if I = u8, and there are 256 items in an ArenaSet, further calls to intern will fail with this error.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl PartialEq for Error

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Error

impl Eq for Error

impl StructuralPartialEq for Error
