Associated Constants

`pub const MAX_VARINT_BYTES: u8`[src]

The maximum length of varint that is necessary to represent this number

`pub const MAX_LAST_VARINT_BYTE: u8`[src]

The maximum value of the last byte if the varint is MAX_VARINT_BYTES long such that the varint would not overflow the target

Required methods

`pub fn vector_to_num(res: [u8; 16]) -> Self`[src]

Converts a 128-bit vector to this number

Note: Despite operating on 128-bit SIMD vectors, these functions accept and return static arrays due to a lack of optimization capability by the compiler when passing or returning intrinsic vectors.

`pub fn num_to_vector_stage1(self) -> [u8; 16]`[src]

Splits this number into 7-bit segments for encoding

`pub fn zigzag(from: Self::Signed) -> Self`[src]

ZigZag encodes this value

`pub fn unzigzag(self) -> Self::Signed`[src]

ZigZag decodes this value
