decodeMessage

Declaration

mutating func decodeMessage<D>(decoder: inout D) throws where D : Decoder

Summary

Decode all of the fields from the given decoder.
This is a simple loop that repeatedly gets the next field number
from decoder.nextFieldNumber() and then uses the number returned
and the type information from the original .proto file to decide
what type of data should be decoded for that field. The corresponding
method on the decoder is then called to get the field value.
This is the core method used by the deserialization machinery. It is
public to enable users to implement their own encoding formats by
conforming to Decoder; it should not be called otherwise.
Note that this is not specific to binary encodng; formats that use
textual identifiers translate those to field numbers and also go
through this to decode messages.

Throws

• an error on failure or type mismatch. The type of error thrown depends on which decoder is used.

Parameters

Name	Type	Summary
decoder	D	a Decoder; the Message will call the method corresponding to the type of this field.
