Trait OpacityQuery 

pub trait OpacityQuery:
    QueryData
    + Send
    + Sync {
    type Cx: SystemParam;

    // Required method
    fn apply_opacity(
        this: &mut Self::Item<'_, '_>,
        cx: &mut <Self::Cx as SystemParam>::Item<'_, '_>,
        opacity: f32,
    );
}

A QueryData with an opacity value.

Required Associated Types

type Cx: SystemParam

Required Methods

fn apply_opacity( this: &mut Self::Item<'_, '_>, cx: &mut <Self::Cx as SystemParam>::Item<'_, '_>, opacity: f32, )

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
