Given a list of targets and an algorithm decide which target the request should be forwarded to.

Summary

algorithm()

The algorithm used to select which target to forward requests to (when there is more than one matching target).

Tries to choose a target from the list of targets to send the request to based on the chosen algorithm.

A guard for testing if an algorithm is supported.

@type algorithm() :: :least_connections | :random | :round_robin | :sticky

The algorithm used to select which target to forward requests to (when there is more than one matching target).

@spec choose(Plug.Conn.t(), [Wayfarer.Router.target()], Wayfarer.Router.algorithm()) ::
  {:ok, Wayfarer.Router.target()} | :error

Tries to choose a target from the list of targets to send the request to based on the chosen algorithm.
