Struct LifetimeTransitivity 

pub struct LifetimeTransitivity<'env> { /* private fields */ }

Collect all lifetimes that are either longer_or_shorter

Implementations

impl<'env> LifetimeTransitivity<'env>

pub fn longer(env: &'env LifetimeEnv) -> Self

Returns a new LifetimeTransitivity that finds all longer lifetimes.

pub fn shorter(env: &'env LifetimeEnv) -> Self

Returns a new LifetimeTransitivity that finds all shorter lifetimes.

pub fn longer_than( env: &'env LifetimeEnv, named: &NamedLifetime, ) -> Vec<&'env NamedLifetime>

Returns all the lifetimes longer than a provided NamedLifetime.

pub fn shorter_than( env: &'env LifetimeEnv, named: &NamedLifetime, ) -> Vec<&'env NamedLifetime>

Returns all the lifetimes shorter than the provided NamedLifetime.

pub fn visit(&mut self, named: &NamedLifetime)

Visits a lifetime, as well as all the nodes it’s transitively longer or shorter than, depending on how the LifetimeTransitivity was constructed.

pub fn finish(self) -> Vec<&'env NamedLifetime>

Returns the transitively reachable lifetimes.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
