UdpStreamParallelism

hopr_lib::prelude

Enum UdpStreamParallelism 

Source 
pub enum UdpStreamParallelism {
    Auto,
    Specific(NonZero<usize>),
}
Expand description

Determines how many parallel readers or writer sockets should be bound in ConnectedUdpStream.

Each UDP socket is bound with SO_REUSEADDR and SO_REUSEPORT to facilitate parallel processing of send and/or receive operations.

NOTE: This is a Linux-specific optimization, and it will have no effect on other systems.

The default is Specific(1).

Always use into_num_tasks or split_evenly_with to determine the correct number of sockets to spawn.

Variants§

§

Auto

Bind as many sender or receiver sockets as given by std::thread::available_parallelism.

§

Specific(NonZero<usize>)

Bind a specific number of sender or receiver sockets.

Implementations§

Source§

impl UdpStreamParallelism

Source

pub fn split_evenly_with(self, other: UdpStreamParallelism) -> (usize, usize)

Returns the number of sockets for this and the other instance when they evenly split the available CPU parallelism.

Source

pub fn into_num_tasks(self) -> usize

Calculates the actual number of tasks for this instance.

The returned value is never more than the maximum available CPU parallelism.
