Parse TOML strings in Rust using the `toml` crate and `from_str` to convert text into usable data structures.
Use the toml crate to parse TOML strings into Rust structs or Value types.
use toml::from_str;
let toml_str = r#"
name = "example"
version = "0.1.0"
"#;
let config: Result<serde_json::Value, _> = from_str(toml_str);
Install the crate with cargo add toml and derive Deserialize on your struct if using a custom type.
Parsing TOML means turning a text configuration file into data your program can use. It's like reading a recipe card and putting the ingredients into your kitchen so you can start cooking. You use this whenever your app needs to read settings from a file like Cargo.toml or book.toml.
