Trait ReadableOptionVec 

pub trait ReadableOptionVec<I: VecIndex, T: VecValue + Default> {
    // Required methods
    fn collect_or_default(&self) -> Vec<T>;
    fn collect_one_flat(&self, index: I) -> Option<T>;
}

Extension methods for ReadableVec<I, Option<T>>.

Required Methods

fn collect_or_default(&self) -> Vec<T>

Collect all values, replacing None with T::default().

fn collect_one_flat(&self, index: I) -> Option<T>

Flattens Option<Option<T>> → Option<T>.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
