Module matching 

This module is responsible for matching a search pattern against a node in the AST. In the process of matching, placeholder values are recorded.

Macros

fail_match 🔒

match_error 🔒

Structs

Match

Information about a match that was found.

MatchFailed 🔒

An “error” indicating that matching failed. Use the fail_match! macro to create and return this.

MatchFailureReason 🔒

Matcher 🔒

Checks if our search pattern matches a particular node of the AST.

PatternIterator 🔒

PlaceholderMatch 🔒

Information about a placeholder bound in a match.

Enums

Phase 🔒

Which phase of matching we’re currently performing. We do two phases because most attempted matches will fail and it means we can defer more expensive checks to the second phase.

Constants

RECORDING_MATCH_FAIL_REASONS

Functions

get_match 🔒

Checks if code matches the search pattern found in search_scope, returning information about the match, if it does. Since we only do matching in this module and searching is done by the parent module, we don’t populate nested matches.
