-/// Resource limits for decoding.
-///
-/// Limits can be either *strict* or *non-strict*. Non-strict limits are best-effort
-/// limits where the library does not guarantee that limit will not be exceeded. Do note
-/// that it is still considered a bug if a non-strict limit is exceeded, however as
-/// some of the underlying decoders do not support not support such limits one cannot
-/// rely on these limits being supported. For stric limits the library makes a stronger
-/// guarantee that the limit will not be exceeded. Exceeding a strict limit is considered
-/// a critical bug. If a decoder cannot guarantee that it will uphold a strict limit it
-/// *must* fail with `image::error::LimitErrorKind::Unsupported`.
-///
-/// Currently the only strict limits supported are the `max_image_width` and `max_image_height`
-/// limits, however more will be added in the future. [`LimitSupport`] will default to support
-/// being false and decoders should enable support for the limits they support in
-/// [`ImageDecoder::set_limits`].
-///
-/// The limit check should only ever fail if a limit will be exceeded or an unsupported strict
-/// limit is used.
