I ran this `dfx deploy` and got this issue

```auto
aused by: The build step failed for canister 'd6g4o-amaaa-aaaaa-qaaoq-cai' (minter)
Caused by: Failed to build Rust canister 'minter'.
Caused by: Failed to create <Type>CanisterInfo for canister 'minter'.
Caused by: Crate `minter` is not a bin or cdylib

```

my `Cargo.toml`

```auto
[[bin]]
name = "minter"
path = "src/main.rs"

```

Hey guy, I think maybe you forget to put this library into Cargo.toml:

```auto
[lib]
crate-type = [ 
  "cdylib", 
]

```
