Trait KeyUsageSliceHelper 

pub(crate) trait KeyUsageSliceHelper {
    // Required methods
    fn usage_intersection(&self, other: &[KeyUsage]) -> Vec<KeyUsage>;
    fn normalized_value(&self) -> Vec<KeyUsage>;
    fn ensure_only_contain_entries_from(
        &self,
        allowed: &[KeyUsage],

}

The trait providing helper functions for &[KeyUsage]

Required Methods

fn usage_intersection(&self, other: &[KeyUsage]) -> Vec<KeyUsage>

https://w3c.github.io/webcrypto/#concept-usage-intersection

fn normalized_value(&self) -> Vec<KeyUsage>

https://w3c.github.io/webcrypto/#concept-normalized-usages

fn ensure_only_contain_entries_from(&self, allowed: &[KeyUsage]) -> ErrorResult

Ensure that the key usage list only contains entries which are in allowed. If the key usage list contains an entry which is not in allowed, then throw a SyntaxError. Note that, if allowed is set to empty, it throws a SyntaxError when the key usage list is not empty.
