Struct haproxy_config::config::Config

pub struct Config {
    pub global: Global,
    pub default: Default,
    pub frontends: HashMap<Name, Frontend>,
    pub backends: HashMap<Name, Backend>,
    pub listen: HashMap<Name, Listen>,
    pub userlists: HashMap<Name, Userlist>,
}

A haproxy config where everything except config and options are fully typed. Can be created from a list of Sections using TryFrom. This type does not borrow its input.

Returns Err if the config contains errors or sections or grammar we don not supported. For example conditional blocks.

Examples

Build a config from a list of just parsed sections.

use haproxy_config::parse_sections;
use haproxy_config::Config;

let file = include_str!("../tests/medium_haproxy.cfg");
let sections = parse_sections(file).unwrap();

let config = Config::try_from(&sections).unwrap();

The same as above however we filter out unknown lines that would result in an error. This only works for lines above the first section as anything unknown after a section starts is parsed as a config option.

use haproxy_config::parse_sections;
use haproxy_config::{Config, Section};

let file = include_str!("../tests/unsupported/nonesens.cfg");
let sections = dbg!(parse_sections(file).unwrap());
let supported_sections: Vec<_> = sections.into_iter().filter(|s| !std::matches!(s,
Section::UnknownLine{..})).collect();

let config = Config::try_from(&supported_sections).unwrap();
 
// `nonesens.cfg` contained the line `this will be seen as config unfortunatly`
// its stats frontend. This is not recognised as an error unfortunatly:
assert_eq!(config.frontends
    .get("stats")
    .unwrap()
    .config.get("this")
    .unwrap()
    .as_ref()
    .unwrap(), "will be seen as a config value unfortunatly");
