Enum shawshank::Error

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

Errors that may occur when using an ArenaSet.

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.
