Enum ParseStrategy 

pub enum ParseStrategy {
    TopDownCondensed,
    IndexedCondensed,
    AstarZero {
        stop_at_first_goal: bool,
        beam: Option<f64>,
    },
}

Frontend-friendly parsing strategy without borrowed heuristic tables.

Variants

TopDownCondensed

Parent-driven condensed intersection.

IndexedCondensed

Child-indexed condensed intersection.

AstarZero

Generic A* with the zero heuristic.

Fields

stop_at_first_goal: bool

Stop once the highest-ranked complete derivation is found.

beam: Option<f64>

Optional merit threshold.

Implementations

impl ParseStrategy

pub fn materialization_strategy(&self) -> MaterializationStrategy<'static>

Convert this owned frontend choice into the core strategy type.

Trait Implementations

impl Clone for ParseStrategy

fn clone(&self) -> ParseStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ParseStrategy

impl Debug for ParseStrategy

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

Formats the value using the given formatter.

impl PartialEq for ParseStrategy

fn eq(&self, other: &ParseStrategy) -> 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.
