Trait ToLvError

pub trait ToLvError {
    // Required method
    fn description(&self) -> Cow<'_, str>;

    // Provided methods
    fn code(&self) -> LVStatusCode { ... }
    fn is_error(&self) -> bool { ... }
    fn source(&self) -> Cow<'_, str> { ... }
    fn write_error(&self, error_cluster: &mut ErrorClusterPtr<'_>) -> Result<()> { ... }
}

A trait that can be implemented on types to allow them to be written into a error cluster with ToLvError::write_error.

Required Methods

fn description(&self) -> Cow<'_, str>

The description of the error;

Provided Methods

fn code(&self) -> LVStatusCode

The code for the error. Default is 42.

fn is_error(&self) -> bool

True if is error. Default is true.

fn source(&self) -> Cow<'_, str>

The source of the error if available. Default: none.

fn write_error(&self, error_cluster: &mut ErrorClusterPtr<'_>) -> Result<()>

Write into the LabVIEW Error Pointer.

The pointer is the type that is recieved through the Call Library Node so there is no need to deal with references before this point.

This requires the link feature to enable string manipulation.
