Having a problem with arguments to command containing underscores.

[TheRealSalmon]

I'm using tauri with leptos. Here is my tauri-side code:

#[command]
fn submit_data(
    datatype: &str,
) {
    println!("received: {datatype}")
}

Here is my leptos-side code:

#[derive(Deserialize, Serialize)]
pub struct SubmitDataArgs {
    datatype: String,
    // timestamp: DateTime<Utc>,
    // value: f64,
    // unit: String,
}

impl SubmitDataArgs {
    pub fn new(
        datatype: DataType,
    ) -> Self {
        Self {
            datatype: datatype.to_string(),
        }
    }
}

pub fn submit_data(
    data_type: DataType,
) {
    spawn_local(async move {
        let args = to_value(
            &SubmitDataArgs::new(
                data_type,
            )
        ).unwrap();
        invoke("submit_data", args).await;
    });
}

The code works when the argument name is datatype. However, it doesn't work when the argument name is data_type. Is there a reason the underscore breaks commands/invoke?

Is there a reason the underscore breaks commands/invoke?

The command arguments will be converted to what's considered standard in JS, so data_type in rust will be dataType in javascript. You can disable this by changing the command annotation to this

#[tauri::command(rename_all = "snake_case")]

thank you!
