Fired every time a header is parsed.
Syntax
- (void)onHeader:(int)partIndex :(NSString*)field :(NSData*)value;
func onHeader(_ partIndex: Int32, _ field: String, _ value: Data)
Remarks
The PartIndex parameter contains the index of the part containing the current header. If the header is from the MIME body, this value will be -1.
