Function haproxy_config::parse_sections

pub fn parse_sections(input: &str) -> Result<Vec<Section<'_>>, Error<'_>>

Parse a string representing a haproxy config to list of sections. Preservers comments and the order of the sections and their options. Unknown sections will result in multiple UnknownLine entries.

You can build a more strongly typed Config struct from the output, see example below.

Examples

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

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

// Build a config from the sections
let config = Config::try_from(sections.as_slice()).unwrap();
