Enum eye_hal::platform::Context

pub enum Context<'a> {
    Custom(Box<dyn ContextTrait + Send + 'a>),
    V4l2(Context),
}

Platform context

Leaky abstraction: if you require access to platform specific features, match the enum instance to get the underlying HAL implementation.

A context is used to query platform properties, available devices and more.

Variants

Custom(Box<dyn ContextTrait + Send + 'a>)

Can be used to wrap your own struct

V4l2(Context)

Video4Linux2 context
