Traverseringsregler

Tradladdaren:

• normaliserar kallsokvagar lexikalt;
• avvisar tomma include-sokvagar;
• loser relativa includes fran filen som deklarerade dem;
• bevarar absoluta include-sokvagar;
• detekterar rekursiva include-cykler;
• hoppar over filer som redan laddats via en annan include-gren.

ConfigTreeOptions kan vanda syskonens include-traversering:

#![allow(unused)]
fn main() {
use rust_config_tree::{ConfigTreeOptions, IncludeOrder};

let options = ConfigTreeOptions::default().include_order(IncludeOrder::Reverse);
let _ = options;
}

Sokvagshjalpare

Sokvagshjalparna ar bara lexikala. De loser inte symboliska lankar och kraver inte att sokvagar finns:

• absolutize_lexical(path)
• normalize_lexical(path)
• resolve_include_path(parent_path, include_path)
