Functions for encoding typed integers in array buffers.

Functions

f
decode(
buf: Uint8Array,
offset?
): [bigint, number]

Given a non empty buf, starting at offset (default: 0), begin decoding bytes as VarInt encoded bytes, for a maximum of 10 bytes (offset + 10). The returned tuple is of the decoded varint 32-bit number, and the new offset with which to continue decoding other data.

f
decode32(
buf: Uint8Array,
offset?
): [number, number]

Given a buf, starting at offset (default: 0), begin decoding bytes as VarInt encoded bytes, for a maximum of 5 bytes (offset + 5). The returned tuple is of the decoded varint 32-bit number, and the new offset with which to continue decoding other data.

f
encode(
num: bigint | number,
buf?: Uint8Array,
offset?
): [Uint8Array, number]

Takes unsigned number num and converts it into a VarInt encoded Uint8Array, returning a tuple consisting of a Uint8Array slice of the encoded VarInt, and an offset where the VarInt encoded bytes end within the Uint8Array.
