Struct LabJackGuard 

pub(crate) struct LabJackGuard {
    pub(crate) handle: i32,
}

RAII guard that stops streaming and closes the LabJack handle on drop.

The sampling loop exits through several error and shutdown paths, so cleanup is tied to ownership of the handle instead of each branch remembering to close the device.

Fields

handle: i32

LJM device handle to stop and close.

Trait Implementations

impl Drop for LabJackGuard

fn drop(&mut self)

Stops any active LabJack stream and closes the device handle.

Errors from LJM are ignored, since there is nothing useful to do with them during cleanup.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
