Functions

decode	ssse3 Decodes a single varint from the input slice. Requires SSSE3 support.
decode_eight_u8_unsafe⚠	ssse3 Decodes four adjacent varints into u8's simultaneously. Requires SSSE3 support. Does not perform overflow checking and may produce incorrect output.
decode_four_unsafe⚠	ssse3 Decodes four adjacent varints simultaneously. Target types must fit within 16 bytes when varint encoded. Requires SSSE3 support.
decode_two_unsafe⚠	ssse3 Decodes two adjacent varints simultaneously. Target types must fit within 16 bytes when varint encoded. Requires SSSE3 support.
decode_two_wide_unsafe⚠	avx2 Experimental. May have relatively poor performance. Decode two adjacent varints simultaneously from the input pointer. Requires AVX2. Allows for decoding a pair of u64 values. For smaller values, the non-wide variation of this function will probably be faster.
decode_unsafe⚠	ssse3 Decodes a single varint from the input pointer. Requires SSSE3 support. Returns a tuple containing the decoded number and the number of bytes read.
decode_zigzag	ssse3 Convenience function for decoding a single varint in ZigZag format from the input slice. See also: decode
encode	sse2 Encodes a single number to a varint. Requires SSE2 support.
encode_to_slice	sse2 Encodes a single number to a varint, and writes the resulting data to the slice. Returns the number of bytes written (maximum 10 bytes).
encode_unsafe⚠	sse2 Encodes a single number to a varint. Requires SSE2 support.
encode_zigzag	sse2 Convenience function for encoding a single signed integer in ZigZag format to a varint. See also: encode
