Method resolve_through_prefix_keys

src/completion/array_shape.rs:483–497

Walk through `prefix_keys` to resolve the inner type of a nested array shape. Given a raw type like `array{meta: array{page: int, total: int}}` and prefix keys `["meta"]`, returns `Some(PhpType)` for `array{page: int, total: int}`.

        &self,
        raw_type: &PhpType,
        prefix_keys: &[String],

    /// Given a raw type like `array{meta: array{page: int, total: int}}` and
    /// prefix keys `["meta"]`, returns `Some(PhpType)` for `array{page: int, total: int}`.

        if prefix_keys.is_empty() {
            return Some(raw_type.clone());
        }
