Attribute Macro bevy_defer::async_access

#[async_access]

Mirror an impl block to an async access component.

Requirements

• For type MyResource, there must be a type AsyncMyResource with an accessible field 0 being AsyncResource<MyResource>. This is the semantics of the derive macros.

• All functions must have &self or &mut self receivers.

• Outputs must be 'static.

• Does not support async functions, since it’s currently difficult to get a static future with a self receiver. Return impl Future + 'static instead.

use module::{Character, AsyncCharacter};
#[async_access]
impl Character {
    fn get_name(&self) -> String {
        ..
    }
    fn shoot(&mut self, angle: f32) {
        ..
    }
}

Arguments

• #[async_access(must_exist)]

  This will unwrap the results instead of returning AccessResult. Useful on resources that should always be available.
