Struct RuleTreeSet 

pub struct RuleTreeSet<T> { /* private fields */ }

Implementations

impl<T> RuleTreeSet<T>

pub fn get_num_nt(&self) -> VarId

pub fn get_tree(&self, var: VarId) -> Option<&GrTree>

pub fn get_trees_iter(&self) -> impl Iterator<Item = (VarId, &GrTree)>

Returns all the non-empty trees

pub fn get_vars(&self) -> impl Iterator<Item = VarId> + '_

Returns all the variables corresponding to a non-empty tree

pub fn get_next_available_var(&self) -> VarId

Returns a variable ID that doesn’t exist yet.

pub fn get_terminals(&self) -> HashSet<TokenId>

Returns a set of all the terminals used in the ruleset.

pub fn set_symbol_table(&mut self, symbol_table: SymbolTable)

pub fn get_symbol_table(&self) -> Option<&SymbolTable>

pub fn set_start(&mut self, start: VarId)

Sets the starting production rule.

pub fn to_str( &self, var: VarId, node: Option<usize>, emphasis: Option<usize>, ) -> String

Builds the string representation of the rule tree set of variable var, optionally starting at node node. If emphasis contains a node ID, this subpart of the tree is emphasized in the string.

pub fn get_log_mut(&mut self) -> &mut BufLog

impl RuleTreeSet<General>

pub fn new() -> Self

pub fn with_log(log: BufLog) -> Self

pub fn get_tree_mut(&mut self, var: VarId) -> &mut GrTree

Gets the tree corresponding to var. Creates it if it doesn’t exist yet.

pub fn set_tree(&mut self, var: VarId, tree: GrTree)

Sets the tree corresponding to var. If the variable already exists, the tree is replaced. Otherwise, the set is enlarged to add it.

pub fn normalize(&mut self)

Normalizes all the production rules.

Trait Implementations

impl BuildFrom<RuleTreeSet<General>> for ProdRuleSet<General>

fn build_from(rules: RuleTreeSet<General>) -> Self
