MARITIME PROJECT news!! :D
aisstream.io updated their #API and I had to fix #json parsing in #AIS pipeline

it relied on getting bytes by position. I learnt it's bad practice only when it broke.. rewrote still without reflection or string allocation tho😁

#buildinpublic #dev #dotnet #backend #csharp

fragment of an updated parsing method, the one that takes a payload as byte array, which arrive in tens/hundreds per sec from web socket, into a c#/grpc object ready to be yeeted in inter service communication. so, earlier this method began with a loop iterating over literal bytes after a FIXED position, right after a JSON property " "MessageType": " extracting its value untill the finishing quote into a string variable.. and it WORKED for whopping about HALF A YEAR, somehow the order of properties in JSON payloads was always the same! after update it isn't anymore. I implemented extracting a span with that message type property and as you can see, comparing it with possible types on byte level, even no strings necessary :)

another half of the AIS parsing method. detailed explanation is in the alt text of the previous picture. here you can see that this way with Spans I handled even the case with PositionReports, of which there are several types with similar names - and not a single loop of byte by byte comparison 😅 also yes, now on aisstream.io we have to enable websocket message compression and there is a new message type for it, but it didn't fit in this one post and will be shown properly later

new method of getting the message type name from a byte JSON payload of an AIS message. no strings! only hardcore working with spans directly! :))))

to be able to compare extracted type names with possible values as readonlyspans, I had to turn the possible values from strings to byte arrays

C# 15 refines how collection expressions are passed to methods, reducing boilerplate while keeping intent clear. See the syntax in action and its impact on everyday .NET code. #csharp #dotnet
