# Script to run all Rust Hyper API examples

# It sets up HYPERD_PATH to point to the hyperd executable.
# Make sure to build the release version of hyperd otherwise the benchmark runs
# much slower
#

# Don't exit on error - we want to continue running other examples even if one fails

# `make download-hyperd`). If neither is present, auto-run the downloader
# — this script only exists to run the examples, so `hyperd` is always
# required.
