Struct antlr_rust::token_factory::ArenaFactory
source · [−]pub struct ArenaFactory<'input, TF, T> { /* private fields */ }Expand description
This is a wrapper for Token factory that allows to allocate tokens in separate arena. It can allow to significantly improve performance by passing Tokens by references everywhere.
Requires &'a Tok: Default bound to produce invalid tokens, which can be easily implemented
like this:
lazy_static!{ static ref INVALID_TOKEN:Box<CustomToken> = ... }
impl Default for &'_ CustomToken {
fn default() -> Self { &**INVALID_TOKEN }
}or if possible just
const INVALID_TOKEN:CustomToken = ...Trait Implementations
