I've tried every way I can imagine to make it work, but it doesn't.

[package]
name = "async_scheduler"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
anyhow = "1.0.75"
bimap = "0.6.3"

daggy = "0.8.0"
derivative = "2.2.0"
fixedbitset = "0.4.2"
mirai-annotations = "1.12.0"
rustsat = { version = "0.2.1", features = ["multiopt"] }
rustsat-minisat = "0.1.1"
scuttle = { version = "0.2.0", default-features = false }
contracts = { version = "0.6.3", features = ["mirai_assertions"] }

Is this project maintained ?

Or, it doesn't work with struct with generics.

Another irking behavior is that it doesn't take environment variables when it has cache of some kind. I have to run cargo clean so it takes up the changes to env vars.

[hermanventer]

The issue with the environmental variable seems real. cargo will rebuild things when it detects changes in compiler flags, but it happily ignores MIRAI_FLAGS. That is probably fixable.

By default, MIRAI will only show you diagnostics for source locations rooted in the crate being built. That is a very much a feature. I am none too sure what you are trying to do here, so I can't say off hand whether this is an issue that needs fixing. Can you add some details in the form of an actual project that I can debug?

It doesn't work with structs with generics.

I just found another issue, it suppresses diagnostics if with print_function_names, which I think is inconsistent

[hermanventer]

print_function_names is a very specialized use of MIRAI. Also, printing diagnostics does not seem universally expected and would not be welcomed by the principal users of the feature.

[hermanventer]

It doesn't work with structs with generics.
