Enum aho_corasick::ErrorKind

pub enum ErrorKind {
    StateIDOverflow {
        max: usize,
    },
    PremultiplyOverflow {
        max: usize,
        requested_max: usize,
    },
}

The kind of error that occurred.

Variants

StateIDOverflow

Fields

max: usize

The maximum possible state ID.

An error that occurs when constructing an automaton would require the use of a state ID that overflows the chosen state ID representation. For example, if one is using u8 for state IDs and builds a DFA with 257 states, then the last state’s ID will be 256 which cannot be represented with u8.

PremultiplyOverflow

Fields

max: usize

The maximum possible state id.

requested_max: usize

The maximum ID required by premultiplication.

An error that occurs when premultiplication of state IDs is requested when constructing an Aho-Corasick DFA, but doing so would overflow the chosen state ID representation.

When max == requested_max, then the state ID would overflow usize.
