Module varint

Variable-length integer encoding and decoding

This module implements Google’s Protocol Buffers variable-length integer encoding. Each byte uses 7 bits for the value and 1 bit to indicate if more bytes follow.

Functions

read

Decodes a unsigned 64-bit integer from a varint

read_i64

Decodes a signed 64-bit integer from a varint using ZigZag encoding

size

Calculates the number of bytes needed to encode a value as a varint

size_i64

Calculates the number of bytes needed to encode a signed integer as a varint

write

Encodes a unsigned 64-bit integer as a varint

write_i64

Encodes a signed 64-bit integer as a varint using ZigZag encoding
