Implementations
sourceimpl Column
impl Column
pub fn with_capacity(component_info: &ComponentInfo, capacity: usize) -> Column
sourcepub unsafe fn initialize(
&mut self,
row: usize,
data: *mut u8,
ticks: ComponentTicks
)
pub unsafe fn initialize(
&mut self,
row: usize,
data: *mut u8,
ticks: ComponentTicks
)
Writes component data to the column at given row.
Assumes the slot is uninitialized, drop is not called.
To overwrite existing initialized value, use replace
instead.
Safety
Assumes data has already been allocated for the given row.
sourcepub unsafe fn replace(&mut self, row: usize, data: *mut u8, change_tick: u32)
pub unsafe fn replace(&mut self, row: usize, data: *mut u8, change_tick: u32)
Writes component data to the column at given row. Assumes the slot is initialized, calls drop.
Safety
Assumes data has already been allocated for the given row.
sourcepub unsafe fn initialize_data(&mut self, row: usize, data: *mut u8)
pub unsafe fn initialize_data(&mut self, row: usize, data: *mut u8)
Safety
Assumes data has already been allocated for the given row.

&mut self,

) -> &mut ComponentTicks
pub unsafe fn get_ticks_unchecked_mut(

) -> &mut ComponentTicks
Safety
index must be in-bounds
sourcepub unsafe fn get_data_ptr(&self) -> NonNull<u8>
pub unsafe fn get_data_ptr(&self) -> NonNull<u8>
Safety
must ensure rust mutability rules are not violated
pub fn get_ticks_ptr(&self) -> *const UnsafeCell<ComponentTicks>
pub fn get_ticks_const_ptr(&self) -> *const ComponentTicks
sourcepub unsafe fn get_data_unchecked(&self, row: usize) -> *mut u8
pub unsafe fn get_data_unchecked(&self, row: usize) -> *mut u8
Safety
- index must be in-bounds
- no other reference to the data of the same row can exist at the same time
- pointer cannot be dereferenced after mutable reference to this
Column
was live
sourcepub unsafe fn get_ticks_unchecked(&self, row: usize) -> &ComponentTicks
pub unsafe fn get_ticks_unchecked(&self, row: usize) -> &ComponentTicks
Safety
index must be in-bounds

&self,
row: usize
) -> *mut ComponentTicks
pub unsafe fn get_ticks_mut_ptr_unchecked(
&self,
row: usize
) -> *mut ComponentTicks
Safety
- index must be in-bounds
- no other reference to the ticks of the same row can exist at the same time
- pointer cannot be dereferenced after mutable reference to this column was live
