The structure that holds information about requested feature application.

The feature will be applied with the given value to all glyphs which are in clusters between start (inclusive) and end (exclusive). Setting start to FEATURE_GLOBAL_START and end to FEATURE_GLOBAL_END specifies that the feature always applies to the entire buffer.

Bufferback to summary
public Buffer(ByteBuffer container)

Creates a new hb_feature_t.Buffer instance backed by the specified container.

Changes to the container's content will be visible to the struct buffer instance and vice versa. The two buffers' position, limit, and mark values will be independent. The new buffer's position will be zero, its capacity and its limit will be the number of bytes remaining in this buffer divided by hb_feature_t#SIZEOF, and its mark will be undefined.

The created buffer instance holds a strong reference to the container object.
