Module coding 

Variable-length integers (RFC 9000 §16) and a bounds-checked reader.

Structs

Reader

A cursor over a byte slice; every read is bounds-checked.

Constants

VARINT_MAX

Largest value a varint can hold (2^62 - 1).

Functions

get_varint

Decodes a single varint from the front of buf.

put_varint

Appends v as a varint. Panics in debug builds when v exceeds VARINT_MAX.

put_varint_fixed

Writes v as a varint of exactly len bytes (used for patched length fields).

varint_len

Encoded size of v in bytes (1, 2, 4 or 8). v must be at most VARINT_MAX.
