Type of failures possible while encoding.

error_to_string e converts error e to its string representation.

Type of wire format encoders.

create () creates a new encoder.

to_string e converts the message assembled in e to a string.

to_bytes e converts the message assembled in e to bytes.

varint i e writes a varint i to e.

zigzag i e zigzag-encodes a varint i and writes it to e.

bits32 i e writes four bytes of i to e.

bits64 i e writes eight bytes of i to e.

bytes b e writes a varint indicating length of b and then b to e.

nested f e applies f to an encoder for a message nested in e.

key (k, pk) e writes a key and a payload kind to e.

encode_exn f x ≡ let e = create () in f x e; to_bytes f.

encode f x ≡ try Some (encode_exn f x) with Failure _ -> None.

int32_of_int fld v returns v truncated to int32. If the value doesn't fit in the range of int32, raises Failure (Overflow fld).

int32_of_int64 fld v returns v truncated to int32. If the value doesn't fit in the range of int32, raises Failure (Overflow fld).
