Trait MaybeResolve

pub trait MaybeResolve<In, Out> {
    // Required method
    fn maybe_resolve(
        self,
        context: In,
        calc: impl Fn(*const (), f32) -> f32,
    ) -> Out;
}

Trait to encapsulate behaviour where we need to resolve from a potentially context-dependent size or dimension into a context-independent size or dimension.

Will return a None if it unable to resolve.

Required Methods

fn maybe_resolve(self, context: In, calc: impl Fn(*const (), f32) -> f32) -> Out

Resolve a dimension that might be dependent on a context, with None as fallback value

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.
