Trait rtest::FromContext

pub trait FromContext {
    type Context;

    // Required methods
    fn from_context(context: &Self::Context) -> Option<Resource<Self>>
       where Self: Sized;
    fn into_context(context: &Self::Context, res: Resource<Self>)
       where Self: Sized;
    fn get_resource_id() -> ResourceId;
}

FromContext must be defined for all resources to be used within tests. rather than doing this manually, you can use the derive macro

use rtest_derive::FromContext;

#[derive(FromContext)]
struct FileInfo {
    name: String,
}
