yule_log_macros

Derive macros for the [yule_log](https://crates.io/crates/yule_log] ULOG) ULOG parser.

Features

#[derive(ULogData)]: Maps ULOG subscriptions directly into your structs.
#[derive(ULogMessages)]: Aggregates your structs into a single streaming interface.
Forward unknown messages: Capture raw ULOG messages via #[yule_log(forward_other)].
Memory Efficient: Preserves the streaming nature of the yule_log parser.

Quickstart

For more information, see: [yule_log](https://crates.io/crates/yule_log] ULOG).

Cargo.toml

yule_log = { version = "0.3.0", features = ["macros"] }

Define mappings

#[derive(ULogData)]
pub struct VehicleLocalPosition {
pub timestamp: u64,
pub x: f32,
pub y: f32,
pub z: f32,
}

Create an enum

#[derive(ULogMessages)]
pub enum LoggedMessages {
    VehicleLocalPosition(VehicleLocalPosition),
    #[yule_log(forward_other)]
    Other(yule_log::model::msg::UlogMessage),
}

Iterate over data

let stream = LoggedMessages::stream(reader)?;
for msg_res in stream {
    let msg = msg_res?;
    match msg {
        LoggedMessages::VehicleLocalPosition(v) => println!("x={} y={} z={}", v.x, v.y, v.z),
        LoggedMessages::Other(msg) => println!("Other message: {:?}", msg),
    }
}
