Struct tantivy_stacker::MemoryArena

pub struct MemoryArena { /* private fields */ }

The MemoryArena

Implementations

impl MemoryArena

pub fn mem_usage(&self) -> usize

Returns an estimate in number of bytes of resident memory consumed by the MemoryArena.

Internally, it counts a number of 1MB pages and therefore delivers an upperbound.

pub fn len(&self) -> usize

Returns the number of bytes allocated in the arena.

pub fn is_empty(&self) -> bool

pub fn write_at<Item: Copy + 'static>(&mut self, addr: Addr, val: Item)

pub fn read<Item: Copy + 'static>(&self, addr: Addr) -> Item

Read an item in the memory arena at the given address.

Panics

If the address is erroneous

pub fn slice(&self, addr: Addr, len: usize) -> &[u8]

pub fn slice_from(&self, addr: Addr) -> &[u8]

pub fn slice_from_mut(&mut self, addr: Addr) -> &mut [u8]

pub fn slice_mut(&mut self, addr: Addr, len: usize) -> &mut [u8]

pub fn allocate_space(&mut self, len: usize) -> Addr

Allocates len bytes and returns the allocated address.

Trait Implementations

impl Default for MemoryArena

fn default() -> MemoryArena

Returns the “default value” for a type.
