Native eager-dispatch fast path

Source: R/dispatch.R
dispatch.Rd

Dispatch a call through a dispatcher()'s executable cache, compiling on a miss. An input the dispatcher cannot execute is an error, named after the offending argument; there is no fallback for the caller to take.

Usage

dispatch(dispatcher, args)

dispatcher_size(dispatcher)

Arguments

dispatcher

(Dispatcher)
A dispatcher from dispatcher().

args

(list)
The (already evaluated) argument list of the call.

Value

dispatch() returns the call's result. With backend = "pjrt" that is the output buffers wrapped into "AnvlArray"s and re-nested by the compile callback's out_tree (see dispatcher()); with any other backend it is whatever the compiled closure returned.

dispatcher_size() returns the number of compiled executables the dispatcher currently caches.
