# the previous scheduler in the compile sequence
sched = []

# Since meson and cargo tries build in parallel, this can cause significant load
# when meson tries to launch N instances of cargo and cargo tries to compile N files
# in parallel (N*N compiler instances in total).
#
# To prevent this from happening, we try to force meson to build them sequentially
# by making the "current" scheduler depend on another scheduler.
# To add a new scheduler, assign the output of your custom_target to sched
# and add sched as a dependency to your custom_target. For example:
#
# sched = custom_target('scx_mysched',
#                       ...
#                       depends: [mydep, sched],
#                       build_always_stale: true)
