Macro nbdkit::plugin

macro_rules! plugin {
    ( $cls:path { $($feat:ident),* } ) => { ... };
}

Register your plugin with NBDKit.

Declare which optional methods it supports by supplying each as an argument.

Examples

struct MyPlugin{
    // ...
}
impl Server for MyPlugin {
    fn get_size(&self) -> Result<i64> {
        // ...
    }

    fn name() -> &'static str {
        "my_plugin"
    }

    fn open(_readonly: bool) -> Result<Box<dyn Server>> {
        // ...
    }

    fn read_at(&self, buf: &mut [u8], offs: u64) -> Result<()> {
        // ...
    }
    fn write_at(&self, buf: &[u8], offs: u64, flags: Flags) -> Result<()> {
        // ...
    }
}

plugin!(MyPlugin {write_at});
