Function parameter_hints 

Source

    range: Option<WireRange>,
) -> Vec<Value>
Expand description

Generates inlay hints for function and method parameters.

This function traverses the AST and identifies function calls, adding inlay hints for parameter names based on the builtin signatures database from the perl-builtins crate. Any builtin with a known signature will produce parameter name hints for its arguments.

§Arguments

  • ast - The root node of the AST to traverse.
  • to_pos16 - A function that converts a byte offset to a (line, character) tuple.
  • range - An optional range to filter the inlay hints.

§Returns

A vector of serde_json::Value objects, each representing an inlay hint.
