Function	Description
`slice`	Returns a byte slice.
`equal`	Returns whether two byte sequences are equal.
`starts_with`	Returns whether buf starts with prefix.
`ends_with`	Returns whether buf ends with suffix.
`index_of`	Returns the first index of needle in buf, or -1 when it is absent.
`push_u8`	Appends a single u8 value to a byte sequence.
`read_u8`	Reads a u8 value at the given offset.
`read_u16_be`	Reads a big-endian u16 at the given offset.
`read_u16_le`	Reads a little-endian u16 at the given offset.
`write_u16_be`	Encodes a big-endian u16 value.
`write_u16_le`	Encodes a little-endian u16 value.
