Compiler error: thread rustc panicked at Box<dyn Any>

[infiniwave]

Error occurs at the encode and decode functions from encryption. Removing those stops this error from occurring. This is likely a bug in the Rust compiler.

Corresponding issue in the Rust repository: rust-lang/rust#97885

error: internal compiler error: compiler/rustc_infer/src/infer/error_reporting/need_type_info.rs:856:33: unexpected path: def=aes_gcm::aead::generic_array::GenericArray substs=[_, _] path=Path { span: src/services/encryption.rs:53:25: 53:30 (#0), res: Def(TyAlias, DefId(180:97 ~ aes_gcm[7ab9]::Nonce)), segments: [PathSegment { ident: Nonce#0, hir_id: Some(HirId { owner: DefId(0:223 ~ easylink[c894]::services::encryption::encode), local_id: 61 }), res: Some(Err), args: None, infer_args: true }] }

/* backtrace */

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.63.0-nightly (50b00252a 2022-06-06) running on x86_64-unknown-linux-gnu

note: compiler flags: --crate-type bin -C embed-bitcode=no -C debuginfo=2 -C incremental

note: some of the compiler flags provided by cargo are hidden

Issue still occurs with latest version of nightly. Could try downgrading to an older version if this issue is not fixed soon.

Reverting to nightly-2022-06-02 seems to have helped. There were some errors due to me using certain things incorrectly, but after fixing those the code compiles correctly.

Setting the version back to latest nightly seems to compile correctly now.
