Enum GeneratorTableType

pub enum GeneratorTableType {
    Arrays,
    Functions,
}

Different generated parser table variants with different trade-offs

Variants

Arrays

Table is generated as nested static arrays Access time should be relatively good but it produces larger executables.

Functions

Table is an array of function pointers where functions contain match expression for further disambiguation. Uses less statically allocated storage but requires function call and pattern matching.
