# v8-goose downloads a prebuilt librusty_v8 archive into target/<profile>/gn_out
|
|
# and emits a rustc-link-search pointing at it. Cargo caches that build script
|
|
# output and replays it on later builds instead of re-running the script, but
|
|
# the Rust cache action prunes target/ before saving, so a restored cache can
|
|
# keep the replayed link-search while the 131MB archive is gone. Linking then
|
|
# fails with "could not find native static library `rusty_v8`".
|
|
#
|
|
# Drop the cached build script output whenever a directory it advertises is
|
|
# missing, which forces the script to re-run and download the archive again.
