Struct RuleSet 

pub struct RuleSet<L: Language> { /* private fields */ }

规则集合

Implementations

impl<L: Language> RuleSet<L>

pub fn new() -> Self

创建新的规则集合

pub fn add_rule(&mut self, rule: Box<dyn FormatRule<L>>) -> FormatResult<()>

添加规则

pub fn add_rules( &mut self, rules: Vec<Box<dyn FormatRule<L>>>, ) -> FormatResult<()>

批量添加规则

pub fn applicable_rules_for_node<'a>( &'a self, node: &'a RedNode<'_, L>, ) -> impl Iterator<Item = &'a dyn FormatRule<L>> + 'a

获取适用于节点的规则

pub fn applicable_rules_for_token<'a>( &'a self, token: &'a RedLeaf<L>, ) -> impl Iterator<Item = &'a dyn FormatRule<L>> + 'a

获取适用于 Token 的规则

pub fn apply_node_rules<'a>( &self, node: &RedNode<'_, L>, context: &FormatContext<L>, source: &'a str, format_children: &dyn Fn(&RedNode<'_, L>) -> FormatResult<Document<'a>>, ) -> FormatResult<Option<Document<'a>>>

应用所有适用的节点规则，返回第一个成功的 Document

pub fn apply_token_rules<'a>( &self, token: &RedLeaf<L>, context: &FormatContext<L>, source: &'a str, ) -> FormatResult<Option<Document<'a>>>

应用所有适用的 Token 规则，返回第一个成功的 Document

Trait Implementations

impl<L: Language> Default for RuleSet<L>

fn default() -> Self

Returns the “default value” for a type.
