Rtoml

Rtoml is a toml parser that's designed to

1. Acquire values at compile time to a struct.
2. Acquire values at runtime required to work.

At the core, a Toml value is represented by this enum

pub enum TomlValue<'a> {
    Int(i64),
    Float(f64),
    String(String),
    Array(Vec<TomlValue<'a>>),
    Boolean(bool),
    DateTime(DateTime),
    Table(Table<'a>),
}

Usage

For a toml file

[a_table]
value = "hello, world"

We will use the following code to acquire values

use rtoml::prelude::*;
use std::error::Error;

fn main() -> Result<(), TomlError> {
    let mut data = String::new();
    let mut file = File::open(concat!(env!("CARGO_MANIFEST_DIR"), "/templates/test.toml"))?;

    file.read_to_string(&mut data)?;

    let toml = TomlValue::try_from(data.as_str())?;

    if let Some(table) = toml.as_table() {
        if let Some(key_value) = table.get(&TomlKey::from("a_table")) {
            assert_eq!(key.get(
                TomlKey::from("value"),
                TomlValue::Literal(String::from("hello, world"))
            ))
        }
    }

    Ok(())
}

• Table dot . format in table names
• Table arrays
• Serialise derive traits
• Use toml testing repo to run all tests
