pub fn read_path(path: &str, ctx: &Value) -> Result<Value, EvalError>Expand description
Parse path and read the value it resolves to inside ctx.
Thin wrapper: parses path via str::parse (surfacing a parse
failure as EvalError::InvalidPath) then delegates to Path::read.
Callers holding an already-parsed Path (e.g. from an Expr::Path)
should call Path::read directly to avoid re-parsing.
