Expected: Toml to be parsed Actual:

Ruby: 3.0.2 I checked the toml on disk is valid with https://www.toml-lint.com/

Yes, I couldn't get it to parse the following Cargo.toml which works fine with Rust's cargo.

[package]
name = "test"
version = "0.4.0"
edition = "2021"

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

[dependencies]
clap = { version = "4.2.7", features = ["derive"] }
serde = { version = "1.0.163", features = ["derive"] }
serde_json = "1.0.93"
ureq = { version = "2.7.0", features = ["json"] }

This parsed it fine, however. https://github.com/emancu/toml-rb
