Struct bevy::ecs::query::Access [−]
pub struct Access<T> where
T: SparseSetIndex, { /* fields omitted */ }
Expand description
Access
keeps track of read and write accesses to values within a collection.
This is used for ensuring systems are executed soundly.
Implementations
impl<T> Access<T> where
T: SparseSetIndex,
impl<T> Access<T> where
T: SparseSetIndex,
pub fn add_read(&mut self, index: T)
pub fn add_read(&mut self, index: T)
Adds a read access for the given index.
pub fn add_write(&mut self, index: T)
pub fn add_write(&mut self, index: T)
Adds a write access for the given index.
Returns true if this Access
contains a read access for the given index.
Returns true if this Access
contains a write access for the given index.
pub fn read_all(&mut self)
pub fn read_all(&mut self)
Sets this Access
to having read access for all indices.
pub fn clear(&mut self)
pub fn clear(&mut self)
Clears all recorded accesses.
Extends this Access
with another, copying all accesses of other
into this.
pub fn is_compatible(&self, other: &Access<T>) -> bool
pub fn is_compatible(&self, other: &Access<T>) -> bool
Returns true if this Access
is compatible with other
.
Two Access
instances are incompatible with each other if one Access
has a write for
which the other also has a write or a read.
Calculates conflicting accesses between this Access
and other
.
