multiformats.varint — mvxcvi/multiformats 0.2.0

Implementation of an MSB unsigned variable-size integer.

Unsigned integers are serialized 7 bits at a time, starting with the least-significant bits. The highest bit (msb) in each output byte indicates if there is a continuation byte.

decode clj/s

(decode buffer)

Decode a byte array as a varint value. Returns the decoded value.

This is a shorthand for reading the bytes at the beginning of the array and ignoring any extra data.

encode clj/s

(encode value)

Encode a value as a sequence of varint bytes. Returns the encoded byte array.

read-bytes clj/s

(read-bytes data offset)

Read bytes from the byte array at the given offset. Returns a tuple with the decoded varint and the number of bytes read.

write-bytes clj/s

(write-bytes value buffer offset)

Write a value as a varint to a byte array at the given offset. Returns the number of bytes written.
