Module ast_grep_core::matcher

This module defines the core Matcher trait in ast-grep.

Matcher has three notable implementations in this module:

• Pattern: matches against a tree-sitter node based on its tree structure.
• KindMatcher: matches a node based on its kind
• RegexMatcher: matches a node based on its textual content using regex.

Structs

• FindAllNodes
• KindMatcher
• MatchAll

• NodeMatch
  Represents the matched node with populated MetaVarEnv. It derefs to the Node so you can use it as a Node. To access the underlying MetaVarEnv, call get_env method.
• Pattern
• RegexMatcher

Enums

• KindMatcherError
• PatternError
• PatternNode
• RegexMatcherError

Traits

• Matcher
  Matcher defines whether a tree-sitter node matches certain pattern, and update the matched meta-variable values in MetaVarEnv. N.B. At least one positive term is required for matching
