Struct LayoutKey 

pub struct LayoutKey {
    pub view_hash: u64,
    pub generation: u64,
}

Key used to identify a cached layout entry. Combines a view hash with a generation counter for cache invalidation.

Fields

view_hash: u64

generation: u64

Trait Implementations

impl Clone for LayoutKey

fn clone(&self) -> LayoutKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LayoutKey

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

Formats the value using the given formatter.

impl Hash for LayoutKey

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 LayoutKey

fn eq(&self, other: &LayoutKey) -> 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.
