:sig bool DTree::to_bool() :see >types 0_DTree json_decode to_f64 to_u64 :content Reads a `DTree` value as a boolean. String values such as `true`, `yes`, `on`, and `1` read as true. Values such as `false`, `no`, `off`, `0`, and `null` read as false. Numeric values read as true when non-zero. Empty strings read as false. Use this when consuming request data, JSON-decoded values, config trees, or component props where the original input may be string-shaped.
