Detailed Description

HashPatternNode.

Represents a hash pattern in pattern matching.

foo => { a: 1, b: 2 }
       ^^^^^^^^^^^^^^

foo => { a: 1, b: 2, **c }
       ^^^^^^^^^^^^^^^^^^^

foo => Bar[a: 1, b: 2]
       ^^^^^^^^^^^^^^^

foo in { a: 1, b: 2 }
       ^^^^^^^^^^^^^^

Type: PM_HASH_PATTERN_NODE

◆ rest

PM_NODE_ALIGNAS struct pm_node* pm_hash_pattern_node::rest

HashPatternNode::rest.

Represents the rest of the Hash keys and values. This can be named, unnamed, or explicitly forbidden via **nil, this last one results in a NoKeywordsParameterNode.
