## Purpose:
## This class is used to update the list of crates in SRC_URI
## by reading Cargo.lock in the source tree.
##
## See meta/recipes-devtools/python/python3-bcrypt_*.bb for an example
##
## To perform the update: bitbake -c update_crates recipe-name
addtask do_update_crates after do_patch
do_update_crates[depends] = "python3-native:do_populate_sysroot"
do_update_crates[nostamp] = "1"
# The directory where to search for Cargo.lock files
CARGO_LOCK_SRC_DIR ??= "${S}"
do_update_crates() {
nativepython3 - <<EOF
def get_crates(f):

return c_list

crates += get_crates(os.path.join(root, file))
open(os.path.join('${THISDIR}', '${BPN}'+"-crates.inc"), 'w').write(crates)
