encodeQuicVarint
encodeQuicVarint(
value):Uint8Array<ArrayBuffer>
Defined in: packages/format-varint/src/quic/encode-quic-varint.ts:21
Encodes a non-negative integer as a QUIC variable-length integer (RFC 9000 §16): a two-bit length prefix in the first byte, then the value big-endian in 1, 2, 4 or 8 bytes. Always the shortest form.
Used throughout QUIC, HTTP/3 (RFC 9114) and HTTP datagrams and capsules (RFC 9297). Unlike the continuation-bit members of this package, the length is known from the first byte.
Time complexity: O(1).
Parameters
Section titled “Parameters”number
A non-negative safe integer. QUIC allows up to 2^62 - 1; this
function stops at Number.MAX_SAFE_INTEGER.
Returns
Section titled “Returns”Uint8Array<ArrayBuffer>
A fresh buffer of 1, 2, 4 or 8 bytes.
Throws
Section titled “Throws”When value is negative, fractional, or beyond
Number.MAX_SAFE_INTEGER.
