warning: Patch `constant_time_eq v0.4.2 (/root/deps/constant_time_eq-0.3.1)` was not used in the crate graph.
Check that the patched package version and available features are compatible
with the dependency requirements. If the patch has a different version from
what is locked in the Cargo.lock file, run `cargo update` to use the new
version. This may also occur with an optional dependency that is not enabled.
error: package `borsh-derive v1.6.0` cannot be built because it requires rustc 1.77.0 or newer, while the currently active rustc version is 1.75.0-dev
Either upgrade to rustc 1.77.0 or newer, or use
cargo update borsh-derive@1.6.0 --precise ver
where `ver` is the latest version of `borsh-derive` supporting rustc 1.75.0-dev
