varints

A variable length integer encoding implementation inspired by SQLite.

Unstable API.

Consts

maxVarIntLen = 9

the maximal number of bytes a varint can take Source Edit

Procs

proc readVu64(z: openArray[byte]; pResult: var uint64): int {...}{.raises: [],
    tags: [].}

Source Edit

proc writeVu64(z: var openArray[byte]; x: uint64): int {...}{.raises: [], tags: [].}

Write a varint into z. The buffer z must be at least 9 characters long to accommodate the largest possible varint. Returns the number of bytes used. Source Edit
