Struct ViaDeserialize

Source
pub struct ViaDeserialize<T>(pub T);
Expand description

Utility type to deserialize an argument.

This allows you to directly accept a type that implements Deserialize as an argument to a filter or test. The type dereferences into the inner type and it also lets you move out the inner type.

use std::path::PathBuf;
use minijinja::value::ViaDeserialize;

fn dirname(path: ViaDeserialize<PathBuf>) -> String {
    match path.parent() {
        Some(parent) => parent.display().to_string(),
        None => "".to_string()
    }
}

env.add_filter("dirname", dirname);
