Struct pleco_engine::tables::TableBase

pub struct TableBase<T: Sized + TableBaseConst> { /* fields omitted */ }

Generic Heap-stored array of entries. Used for building more specific abstractions.

Objects placed inside must not implement Drop, or else undefined behavior follows. Indexing is done with u64s, and returns a value using a mask of the lower log₂(table size) bits. Collisions are possible using this structure, although very rare.

Methods

impl<T: Sized + TableBaseConst> TableBase<T>

pub fn new() -> Option<TableBase<T>>

Constructs a new TableBase. The size must be a power of 2, or else None is returned.

Safety

Size must be a power of 2/

pub fn get_mut(&mut self, key: u64) -> &mut T

Gets a mutable reference to an entry with a certain key.

pub unsafe fn get_ptr(&self, key: u64) -> *mut T

Gets a mutable pointer to an entry with a certain key.

Safety

Unsafe due to returning a raw pointer that may dangle if the TableBase is dropped prematurely.

pub fn clear(&mut self)

Trait Implementations

impl<T: Sized + TableBaseConst> Drop for TableBase<T>

fn drop(&mut self)

Executes the destructor for this type.
