Enum EntityUpdate 

pub enum EntityUpdate {
    None,
    All,
    Classes(Vec<u32>),
    Ids(Vec<u32>),
    Indexes((usize, usize)),
    Append(usize),
}

We use this to define the extent of entity updates, and its effect on the instance buffer. For example, rebuild all entities, or update specific ones in-place.

Variants

None

All

Performs a complete rebuild of the instance buffer. This is a safe default whenever entities changes, but updating specific IDs or classes can be more efficient.

Classes(Vec<u32>)

Update specific classes in place, without changing the instance buffer size.

Ids(Vec<u32>)

Update specific IDs in place, without changing the instance buffer size.

Indexes((usize, usize))

A range of start and end indexes.

Append(usize)

Append this many to the end

Implementations

impl EntityUpdate

pub fn push_class(&mut self, class: u32)

pub fn push_id(&mut self, id: u32)

Trait Implementations

impl Clone for EntityUpdate

fn clone(&self) -> EntityUpdate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EntityUpdate

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

Formats the value using the given formatter.

impl Default for EntityUpdate

fn default() -> EntityUpdate

Returns the “default value” for a type.

impl PartialEq for EntityUpdate

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