merge(into:from:extensions:partial:options:)
Updates the message by reading a single size-delimited message from the given stream. Delimited format allows a single file or stream to contain multiple messages, whereas normally parsing consumes the entire input. A delimited message is a varint encoding the message size followed by a message of exactly that size.
static func merge<M>(into message: inout M, from stream: InputStream, extensions: (any ExtensionMap)? = nil, partial: Bool = false, options: BinaryDecodingOptions = BinaryDecodingOptions()) throws where M : Message Parameters
- mergingTo
The message to merge the data into.
- from
The
InputStreamto read the data from. The stream is assumed to be ready to read from.- extensions
An
ExtensionMapused to look up and decode any extensions in this message or messages nested within this message’s fields.- partial
If
false(the default), this method will checkisInitializedafter decoding to verify that all required fields are present. If any are missing, this method throwsBinaryDelimited/Error/missingRequiredFields.- options
The BinaryDecodingOptions to use.
Throws
Error or SwiftProtobufError if decoding fails, and for some reading errors; or the underlying InputStream.streamError for a stream error.
