pub struct Access<T> where
T: SparseSetIndex, { /* private fields */ }
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
sourceimpl<T> Access<T> where
T: SparseSetIndex,
impl<T> Access<T> where
T: SparseSetIndex,
pub fn grow(&mut self, bits: usize)
sourcepub fn has_read(&self, index: T) -> bool
pub fn has_read(&self, index: T) -> bool
Returns true if this Access
contains a read access for the given index.
sourcepub fn has_write(&self, index: T) -> bool
pub fn has_write(&self, index: T) -> bool
Returns true if this Access
contains a write access for the given index.
sourcepub fn extend(&mut self, other: &Access<T>)
pub fn extend(&mut self, other: &Access<T>)
Extends this Access
with another, copying all accesses of other
into this.
sourcepub 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.
