configster

Rust library for parsing configuration files

Config file format

The 'option' can be any string with no whitespace.

arbitrary_option = false
max_users = 30

The value for an option following the equal sign may have "attributes" that are separated by a delimiter. The delimiter is specified when calling parse_file():

parse_file("./config_test.conf", ',')

option = Blue, light, shiny
# option = nothing, void, empty, commented_out

An option is not required to be followed by a value. It can be used to disable a default feature.

FeatureOff

API

Calling parse_file() will return a single vector containing a struct (OptionProperties) for each option line in the config file. The attributes for a value are stored in a vector within the "Value" struct.

#[derive(Debug, PartialEq)]
pub struct Value {
    pub primary: String,
    pub attributes: Vec<String>,
}

#[derive(Debug, PartialEq)]
pub struct OptionProperties {
    pub option: String,
    pub value: Value,
}

Example Code

use std::io;

fn main() -> Result<(), io::Error> {

    let config_vec = configster::parse_file("./config_test.conf", ',')?;

    for i in &config_vec {
        println!("Option:'{}' | value '{}'", i.option, i.value.primary);

        for j in &i.value.attributes {
            println!("attr:'{}`", j);
        }
        println!();
    }
    Ok(())
}
