Confusing error message for invalid Cargo.toml file

[SimonSapin]

This Cargo.toml file:

[package]

name = "matches"
version = "0.0.1"
authors = ["Simon Sapin <[email protected]>"]

[lib]
path = "lib.rs"

Gives a confusing error message:

matches/Cargo.toml is not a valid manifest

expected a value of type `array`, but found a value of type `table` for the key `lib`

Adding a lib.name key fixes it, but the error message was not helpful in finding that out.

[package]

name = "matches"
version = "0.0.1"
authors = ["Simon Sapin <[email protected]>"]

[lib]
name = "matches"
path = "lib.rs"

Also, since omitting the [lib] section entirely works, overriding just lib.path should work as well, keeping the default name.

Just ran into this as well. I appears that the bug is that you need more than one key-value pair in the [lib]-section.

I think this is fixed. The error is now expected a value of type stringfor the keylib.name``

Thanks @oli-obk!
