Trait WriteToDescriptorChain 

pub trait WriteToDescriptorChain: WSealed {
    // Required method
    fn write_obj<T: VmediaType>(&mut self, obj: T) -> IoResult<()>;

    // Provided methods
    fn write_response<T: VmediaType>(&mut self, response: T) -> IoResult<()> { ... }
    fn write_err_response(&mut self, code: c_int) -> IoResult<()> { ... }
}

Extension trait for writing objects and responses into the device-writable section of a descriptor chain, after converting them to little-endian representation.

Required Methods

fn write_obj<T: VmediaType>(&mut self, obj: T) -> IoResult<()>

Write an arbitrary object to the guest.

Provided Methods

fn write_response<T: VmediaType>(&mut self, response: T) -> IoResult<()>

Write a command response to the guest.

fn write_err_response(&mut self, code: c_int) -> IoResult<()>

Send code as the error code of an error response.

Dyn Compatibility

This trait is not dyn compatible.

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

Implementors

impl<W> WriteToDescriptorChain for W

where W: Write,

Any implementor of std::io::Write can be used to write virtio-media responses.
