pub struct Options<'a> { /* private fields */ }
Expand description

Options which can be used to configure how a misc device is registered.

Examples

fn example(
    reg: Pin<&mut miscdev::Registration<impl file::Operations<OpenData = ()>>>,
    parent: &dyn RawDevice,
) -> Result {
    miscdev::Options::new()
        .mode(0o600)
        .minor(10)
        .parent(parent)
        .register(reg, fmt!("sample"), ())
}

Implementations

Creates new Options instance with the required fields.

Sets the minor device number.

Sets the device mode.

This is usually an octal number and describes who can perform read/write/execute operations on the device.

Sets the device parent.

Registers a misc device using the configured options.

Allocates a new registration of a misc device and completes the registration with the configured options.
