Trait AbiBackend 

pub trait AbiBackend: Send + Sync {
    // Required method
    fn call(
        &self,
        capability: usize,
        input: &str,
        width: u32,
    ) -> Result<String, String>;
}

Runs a runtime plugin’s capabilities. The native and WASM loaders each implement it; tests can too.

Required Methods

fn call( &self, capability: usize, input: &str, width: u32, ) -> Result<String, String>

Run capability number capability (its index in PluginAbi::capabilities) on input with width cells available (0 when unknown). Err is the plugin’s error message, or the host’s.

Dyn Compatibility

This trait is dyn compatible.

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