Module Protobuf.DecoderSource

Type of failures possible while decoding.

error_to_string e converts error e to its string representation.

Type of wire format decoders.

of_bytes b creates a decoder positioned at start of bytes b.

of_string s creates a decoder positioned at start of string s.

at_end d returns true if d has exhausted its input, and false otherwise.

skip d pk skips the next value of kind pk in d. If skipping the value would exhaust input of d, raises Encoding_error Incomplete.

varint d reads a varint from d. If d has exhausted its input, raises Failure Incomplete.

zigzag d reads a varint from d and zigzag-decodes it. If d has exhausted its input, raises Failure Incomplete.

bits32 d reads four bytes from d. If d has exhausted its input, raises Failure Incomplete.

bits64 d reads eight bytes from d. If d has exhausted its input, raises Failure Incomplete.

bytes d reads a varint indicating length and then that much bytes from d. If d has exhausted its input, raises Failure Incomplete.

nested d returns a decoder for a message nested in d. If reading the message would exhaust input of d, raises Failure Incomplete.

key d reads a key and a payload kind from d. If d has exhausted its input when the function is called, returns None. If d has exhausted its input while reading, raises Failure Incomplete. If the payload kind is unknown, raises Failure Malformed_field.

decode_exn f b ≡ f (create b).

decode f b ≡ try Some (decode_exn f b) with Failure _ -> None

int_of_int32 fld v returns v truncated to int. If the value doesn't fit in the range of int, raises Failure (Overflow fld).

int_of_int64 fld v returns v truncated to int. If the value doesn't fit in the range of int, 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).

bool_of_int64 fld v returns v truncated to bool. If the value doesn't fit in the range of bool, raises Failure (Overflow fld).
