Trait DeviceOps 

pub trait DeviceOps:
    DynClone
    + Send
    + Sync
    + AsAny
    + 'static {
    // Required method
    fn open(
        &self,
        current_task: &CurrentTask,
        devt: DeviceId,
        node: &NamespaceNode,
        flags: OpenFlags,
    ) -> Result<Box<dyn FileOps>, Errno>;
}

Required Methods

fn open( &self, current_task: &CurrentTask, devt: DeviceId, node: &NamespaceNode, flags: OpenFlags, ) -> Result<Box<dyn FileOps>, Errno>

Instantiate a FileOps for this device.

This function is called when userspace opens a file with a DeviceId assigned to this device.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors

impl<F> DeviceOps for F

where F: Clone + Send + Sync + Fn(&CurrentTask, DeviceId, &NamespaceNode, OpenFlags) -> Result<Box<dyn FileOps>, Errno> + 'static,

Allows directly using a function or closure as an implementation of DeviceOps, avoiding having to write a zero-size struct and an impl for it.
