Struct LVUserEvent

pub struct LVUserEvent<T> { /* private fields */ }

Representation of a LabVIEW user event reference with type data.

Where the reference is passed into Rust you can use this typed form to then allow proper type completions of the values.

From LabVIEW you can set the terminal to be adapt to type and handles by value

Example

#[no_mangle]
pub extern "C" fn generate_event_3(lv_user_event: *mut LVUserEvent<i32>) -> LVStatusCode {
   let event = unsafe { *lv_user_event };
   let result = event.post(&mut 3);
   match result {
       Ok(_) => LVStatusCode::SUCCESS,
       Err(err) => err.into(),
   }
}

Implementations

impl<T> LVUserEvent<T>

pub fn post(&self, data: &mut T) -> Result<()>

Generate the user event with the provided data.

Right now the data needs to be a mutable reference as the LabVIEW API does not specify whether it will not be modified.
