Enum StreamBufferSetRequest

pub enum StreamBufferSetRequest {
    AddPayloadBuffer {
        id: u32,
        payload_buffer: Vmo,
        control_handle: StreamBufferSetControlHandle,
    },
    RemovePayloadBuffer {
        id: u32,
        control_handle: StreamBufferSetControlHandle,
    },
}

Manages a set of payload buffers for a stream. This interface is typically inherited along with StreamSink or StreamSource to enable the transport of elementary streams between clients and services.

Variants

AddPayloadBuffer

Adds a payload buffer to the current buffer set associated with the connection. A StreamPacket struct reference a payload buffer in the current set by ID using the StreamPacket.payload_buffer_id field.

A buffer with ID id must not be in the current set when this method is invoked, otherwise the service will close the connection.

Fields

id: u32

payload_buffer: Vmo

control_handle: StreamBufferSetControlHandle

RemovePayloadBuffer

Removes a payload buffer from the current buffer set associated with the connection.

A buffer with ID id must exist in the current set when this method is invoked, otherwise the service will will close the connection.

Fields

id: u32

control_handle: StreamBufferSetControlHandle
