# ### Pre-requisites:
#
# `pact-reference` repo and `PactSwift` repo are on the same folder level
#
# ### Usage:
# ./Support/build_rust_dependencies
#
# In order to minimise the built binary size update $LIBPACT_FFI_DI/Cargo.toml and append the following:
#
# [lib]
# crate-type = ["staticlib"]
#
# [profile.release]
# opt-level = 'z'
# lto = true
# panic = 'abort'
