Enum ProdRule

pub enum ProdRule {
    Var(String, Config),
    Const(ConstValue, Config),
    Op1(String, String, Config),
    Op2(String, String, String, Config),
    Op3(String, String, String, String, Config),
}

A variant-rich enumeration representing different types of production rules used in string synthesis.

It includes variants for handling variables, constants, and operations with differing arities. Each variant encapsulates a production rule as follows:

The Var variant takes a variable name and a configuration, associating this rule with a specific variable in the synthesis problem. The Const variant holds a constant value alongside its configuration, representing fixed values in the synthesis. Variants Op1, Op2, and Op3 capture operations with one, two, and three operands respectively, each carrying the necessary operands as strings and concluding with a configuration object to manage operational parameters or constraints. This structure enables flexible representation of grammatical constructs in syntax-guided synthesis tasks, supporting a wide range of synthesis requirements.

Variants

Var(String, Config)

Const(ConstValue, Config)

Op1(String, String, Config)

Op2(String, String, String, Config)

Op3(String, String, String, String, Config)

Implementations

impl ProdRule

pub fn const_value(&self) -> Option<&ConstValue>

Returns the constant value associated with a specific production rule, if available.

pub fn parse(pair: Pair<'_, Rule>) -> Result<Self, Error>

Parses a Pair object into a ProdRule variant.

Trait Implementations

impl Clone for ProdRule

fn clone(&self) -> ProdRule

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ProdRule

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

Formats the value using the given formatter.

impl Hash for ProdRule

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ProdRule

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