Struct LgAlloc

pub struct LgAlloc {
    pub enabled: Option<bool>,
    pub path: Option<PathBuf>,
    pub background_config: Option<BackgroundWorkerConfig>,
    pub eager_return: Option<bool>,
    pub file_growth_dampener: Option<usize>,
    pub local_buffer_bytes: Option<usize>,
}

Lgalloc configuration

Fields

enabled: Option<bool>

Whether the allocator is enabled or not.

path: Option<PathBuf>

Path where files reside.

background_config: Option<BackgroundWorkerConfig>

Configuration of the background worker.

eager_return: Option<bool>

Whether to return physical memory on deallocate

file_growth_dampener: Option<usize>

Dampener in the file growth rate. 0 corresponds to doubling and in general n to 1+1/(n+1).

local_buffer_bytes: Option<usize>

Size of the per-thread per-size class cache, in bytes.

Implementations

impl LgAlloc

pub fn new() -> Self

Construct a new configuration. All values are initialized to their default (None) values.

pub fn enable(&mut self) -> &mut Self

Enable lgalloc globally.

pub fn disable(&mut self) -> &mut Self

Disable lgalloc globally.

pub fn with_background_config( &mut self, config: BackgroundWorkerConfig, ) -> &mut Self

Set the background worker configuration.

pub fn with_path(&mut self, path: PathBuf) -> &mut Self

Set the area file path.

pub fn eager_return(&mut self, eager_return: bool) -> &mut Self

Enable eager memory reclamation.

pub fn file_growth_dampener(&mut self, file_growth_dapener: usize) -> &mut Self

Set the file growth dampener.

pub fn local_buffer_bytes(&mut self, local_buffer_bytes: usize) -> &mut Self

Set the local buffer size.

Trait Implementations

impl Clone for LgAlloc

fn clone(&self) -> LgAlloc

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for LgAlloc

fn default() -> LgAlloc

Returns the “default value” for a type.

impl PartialEq for LgAlloc

fn eq(&self, other: &LgAlloc) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
