Struct World 

pub struct World(/* private fields */);

A world assigns each rule to one of its branch indices

Implementations

impl World

pub fn new() -> Self

Create a new empty world

pub fn get(&self, rule_path: &RulePath) -> Option<&usize>

Get the branch index for a rule

pub fn insert( &mut self, rule_path: RulePath, branch_idx: usize, ) -> Option<usize>

Insert a branch assignment for a rule

pub fn iter(&self) -> impl Iterator<Item = (&RulePath, &usize)>

Iterate over all branch assignments

Trait Implementations

impl Clone for World

fn clone(&self) -> World

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for World

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

Formats the value using the given formatter.

impl Default for World

fn default() -> World

Returns the “default value” for a type.

impl PartialEq for World

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

impl Serialize for World

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for World

impl StructuralPartialEq for World
