Struct smithay::backend::allocator::dumb::DumbBuffer

pub struct DumbBuffer<A: AsRawFd + 'static> { /* fields omitted */ }

Wrapper around raw DumbBuffer handles.

Implementations

impl<A: AsRawFd + 'static> DumbBuffer<A>

pub fn handle(&self) -> &Handle

Raw handle to the underlying buffer.

Note: This handle will become invalid, once the DumbBuffer wrapper is dropped or the device used to create is closed. Do not copy this handle and assume it keeps being valid.
