Expand description

Control operations capability

This trait represents the ability to perform control operations on a resource, similar to ioctl operations in POSIX systems. Control operations allow querying and modifying device-specific settings and configurations.

Provided Methods§

Source

fn control(&self, command: u32, arg: usize) -> Result<i32, &'static str>

Perform a control operation

§Arguments
  • command - The control command identifier
  • arg - Command-specific argument (often a pointer to data)
§Returns
  • Result<i32, &'static str> - Command-specific return value or error
§Default Implementation

The default implementation returns an error indicating that control operations are not supported by this object.

Source

fn supported_control_commands(&self) -> Vec<(u32, &'static str)>

Get a list of supported control commands

§Returns

A vector of tuples containing (command_id, description) for each supported control command. This can be used for introspection and debugging purposes.

§Default Implementation

The default implementation returns an empty vector, indicating no control commands are supported.
