thread 'rustc' panicked at 'Box<Any>', /rustc/53cb7b09b00cbea8754ffb78e7e3cb521cb8af4b\library\std\src\panic.rs:59:5
note: run with `RUST_BACKTRACE=1` environment variable to display a 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 1.53.0 (53cb7b09b 2021-06-17) running on x86_64-pc-windows-msvc

note: compiler flags: -C opt-level=3 -C embed-bitcode=no

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

query stack during panic:
#0 [codegen_fulfill_obligation] checking if `std::ops::Fn` fulfills its obligations
#1 [resolve_instance] resolving instance `<for<'a> fn(<rust_serialization_benchmark::datasets::log::LogsSchema as alkahest::SchemaUnpack<'a>>::Unpacked) {alkahest_logs_read} as std::ops::Fn<(rust_serialization_benchmark::datasets::log::LogsSchemaUnpacked,)>>::call`
end of query stack
error: aborting due to previous error; 2 warnings emitted

error: could not compile `rust_serialization_benchmark`
