Struct LifetimeNode

pub(crate) struct LifetimeNode {
    pub(crate) lifetime: NamedLifetime,
    pub(crate) shorter: Vec<usize>,
    pub(crate) longer: Vec<usize>,
}

A lifetime, along with ptrs to all lifetimes that are explicitly shorter/longer than it.

This type is internal to [LifetimeGraph]- the ptrs are stored as usizes, meaning that they may be invalid if a LifetimeEdges is created in one LifetimeGraph and then used in another.

Fields

lifetime: NamedLifetime

The name of the lifetime.

shorter: Vec<usize>

Pointers to all lifetimes that this lives at least as long as.

Note: This doesn’t account for transitivity.

longer: Vec<usize>

Pointers to all lifetimes that live at least as long as this.

Note: This doesn’t account for transitivity.

Trait Implementations

impl Clone for LifetimeNode

fn clone(&self) -> LifetimeNode

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LifetimeNode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for LifetimeNode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for LifetimeNode

fn eq(&self, other: &LifetimeNode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
