Struct RingConfigBuilder

Source 
pub struct RingConfigBuilder {
    pub rx_count: u32,
    pub tx_count: u32,
    pub fill_count: u32,
    pub completion_count: u32,
}
Expand description

Builder for the rings that will be created for an XDP socket.

All fields must be a power of two, and both fill_count and completion_count must not be zero.

rx_count OR tx_count may be zero, but not both

Fields§

§rx_count: u32

The maximum number of entries in the RxRing

§tx_count: u32

The maximum number of entries in the TxRing or WakableTxRing

§fill_count: u32

The maximum number of entries in the FillRing or WakableFillRing

§completion_count: u32

The maximum number of entries in the CompletionRing
