Struct Accessor 

pub struct Accessor<Component>(/* private fields */);

Helper to give access to a component via a turbofish-friendly, infix syntax.

Implementations

impl<Component> Accessor<Component>

pub fn from<'c, Container>(&self, container: &'c Container) -> &'c Component

where Container: Has<Component>,

Accesses a component from its container.

This function simply delegates to the trait’s method, but it might be interesting for those who prefer turbofish to annotate types combined with an infix notation.

examples/env.rs (line 27)

fn run_with<E>(env: E)
where
    E: Has<Host> + Has<Port> + Has<Verbosity>,
{
    // Accessing via trait-method + type annotation.
    let host: &Host = env.access();

    // Accessing via free-standing function + turbofish.
    let port = access_from::<Port, _>(&env);

    // Accessing via free-standing function + turbofish + infix.
    let verbosity = access::<Verbosity>().from(&env);

    println!(
        "host: {:?}, port: {:?}, verbosity: {:?}",
        host, port, verbosity
    )
}
