# Proxy build and runtime

# When PROXY_UNOPTIMIZED is set and not empty, unoptimized rust artifacts are produced.
|

# This reduces build time and produces binaries with debug symbols, at the expense of
|
|
# runtime perforamnce.
|
|
#
|
|
# When PROXY_SKIP_TESTS is set and not empty, tests are not run. Otherwise, tests are run
|
|
# against either unoptimized or optimized proxy code, according to PROXY_UNOPTIMIZED.
