toml-rs can't read its own output if the root level object is a list

[liljencrantz]

Sending in a list of integers, e.g. toml::Value::from(vec![toml::Value::from(1), toml::Value::from(2)]) results in a serialized output like [1, 2].

But when trying to deserialize that same output, one gets the error Error: expected a right bracket, found a comma at line 1 column 3.

I don't know if the toml file format allows the root node to be a list or not, so I don't know if this is a bug in the serializer or the deserializer, but I think it's pretty clear that any output that toml-rs spits out, it should be able to read back in.

It should also be noted that if the root object is a list of tables, one gets even trippier output, like

[[]]
file = ".git"
modified = "2020-04-15T17:46:22.776979796+02:00"
size = 4096
type = "directory"
user = "liljencrantz"

[[]]
file = "todo"
modified = "2020-04-14T16:19:16.269954425+02:00"
size = 2020
type = "file"
user = "liljencrantz"

Not sure if that's how it's supposed to look.

I believe this is a bug in the serialization here, really only toml tables can be considered a document to parse later, othrewise serialization is just fragments of a document and may not make sense. There's no way to deserialize a top-level array from a toml document.

Maintenance of this crate has moved to the https://github.com/toml-rs/toml repo. As a heads up, we plan to move toml to be on top of toml_edit, see toml-rs/toml#340.

Closing this out. If this is still a problem, feel free to recreate this issue in the new repo.
