| # libFuzzer needs the -Z flags only nightly accepts, and installing a | |
| # nightly toolchain is not enough to get one: rustup resolves | |
| # rust-toolchain.toml over whatever the action installed, so every run of | |
| # this job since it was written died on `the option Z is only accepted on | |
| # the nightly compiler` before fuzzing a byte. RUSTUP_TOOLCHAIN outranks | |
| # the file and is inherited by the cargo that cargo-fuzz spawns. | |
