Implementations

impl Ability_

pub const COPY: &'static str

pub const DROP: &'static str

pub const STORE: &'static str

pub const KEY: &'static str

pub fn requires(self) -> Ability_

For a struct with ability a, each field needs to have the ability a.requires(). Consider a generic type Foo<t1, …, tn>, for Foo<t1, …, tn> to have ability a, Foo must have been declared with a and each type argument ti must have the ability a.requires()

pub fn required_by(self) -> Vec<Ability_>

An inverse of requires, where x is in a.required_by() iff x.requires() == a
