Struct soak::RawTable

pub struct RawTable<T: Columns> { /* fields omitted */ }

A raw allocation containing parallel arrays of T's fields.

Much like std's RawVec, RawTable manages an allocation for a collection, but without managing the initialization or dropping of its contents. RawTable does not deal directly with elements of type T, but with multiple adjacent arrays of T's fields, shared in a single allocation.

Methods

impl<T: Columns> RawTable<T>

pub fn with_capacity(capacity: usize) -> Self

Create a RawTable with enough space for capacity elements of each field type.

Panics

Panics if the requested capacity exceeds usize::MAX bytes.

Aborts

Aborts on OOM.

pub fn ptr<F>(&mut self, field: Field<T, F>) -> *mut F

Get a pointer to a field array.

pub fn capacity(&self) -> usize

Get the capacity of the allocation.

pub fn reserve_exact(&mut self, used: usize, extra: usize)

Ensure that the table contains enough space for used + extra elements.

Panics

Panics if the requested capacity exceeds usize::MAX bytes.

Aborts

Aborts on OOM.

Trait Implementations

impl<T: Columns> Default for RawTable<T>

fn default() -> Self

Create a RawTable without allocating.

impl<T: Columns> Drop for RawTable<T>

fn drop(&mut self)

Free the underlying buffer but do not drop the arrays' elements.
