pinned_xdp_sender

This module defines PinnedXdpSender which is a convenience wrapper around agave_xdp::transmitter::XdpSender for the case when source address is fixed.

socket_addr_space

sockets

token_bucket

This module contains TokenBucket, which provides ability to limit rate of certain events, while allowing bursts through. KeyedRateLimiter allows to rate-limit multiple keyed items, such as connections.

Functions

bind_in_range

bind_to_unspecified

find_available_port_in_range

Searches for an open port on a given binding ip_addr in the provided range.

find_available_ports_in_range

Searches for several ports on a given binding ip_addr in the provided range.

get_cluster_shred_version

Retrieves cluster shred version from Entrypoint address provided.

get_cluster_shred_version_with_binding

Retrieves cluster shred version from Entrypoint address provided, binds client-side socket to the IP provided.

get_public_ip_addr_with_binding

Determine the public IP address of this machine by asking an ip_echo_server at the given address. This function will bind to the provided bind_addreess.

ip_echo_server

Starts a simple TCP server that echos the IP address of any peer that connects Used by functions like |get_public_ip_addr| and |get_cluster_shred_version|

is_host

is_host_port

parse_host

parse_host_port

parse_port_or_addr

parse_port_range

verify_all_reachable_tcp

Checks if all of the provided TCP ports are reachable by the machine at ip_echo_server_addr. Tests must complete within timeout provided. Tests will run concurrently when possible, using up to 64 threads for IO. This function assumes that all sockets are bound to the same IP, and will panic otherwise.

verify_all_reachable_udp

Checks if all of the provided UDP ports are reachable by the machine at ip_echo_server_addr. Tests must complete within timeout provided. Tests will run concurrently when possible, using up to 64 threads for IO. This function assumes that all sockets are bound to the same IP, and will panic otherwise
