Implementations

impl ObjPool

pub fn with_size<P: AsRef<Path>, S: Into<String>>(
    path: P,
    layout: Option<S>,
    size: usize
) -> Result<Self, Error>

pub fn new<P: AsRef<Path>, S: Into<String>>(
    path: P,
    layout: Option<S>,
    obj_size: usize,
    capacity: usize
) -> Result<Self, Error>

pub fn set_capacity(
    self,
    obj_size: usize,
    data_type: u64,
    capacity: usize
) -> Result<(Self, ArrayQueue<ObjRawKey>), Error>

pub fn with_capacity<P: AsRef<Path>, S: Into<String>>(
    path: P,
    layout: Option<S>,
    obj_size: usize,
    data_type: u64,
    capacity: usize
) -> Result<(Self, ArrayQueue<ObjRawKey>), Error>

pub fn with_initial_capacity<P: AsRef<Path>, S: Into<String>>(
    path: P,
    layout: Option<S>,
    obj_size: usize,
    data_type: u64,
    capacity: usize,
    initial_capacity: usize
) -> Result<(Arc<Self>, Arc<ArrayQueue<ObjRawKey>>), Error>

pub fn update_by_rawkey<O>(
    &self,
    rkey: ObjRawKey,
    data: &[u8],
    offset: O
) -> Result<ObjRawKey, Error> where
    O: Into<Option<usize>>, 

pub fn allocate<'a>(
    &self,
    size: usize,
    data_type: u64,
    arg: impl Into<Option<&'a [u8]>>
) -> Result<ObjRawKey, Error>

pub fn obj_size_get(&self, key: ObjRawKey) -> Result<(usize, ObjRawKey), Error>

pub fn remove(&self, key: ObjRawKey) -> Result<(), Error>

pub unsafe fn get_by_rawkey(&self, rkey: ObjRawKey, buf: &mut [u8]) -> ObjRawKey

Safety

Should be called on valid ObjRawKey only

pub fn set_rm_on_drop(&mut self, rm_pool: bool)

pub fn iter(&self) -> ObjPoolIterⓘ

Important traits for ObjPoolIter

impl Iterator for ObjPoolIter type Item = ObjRawKey;

pub fn thread_arena_init(&self) -> Result<u32, Error>

pub fn thread_arena_get(&self) -> Result<u32, Error>

pub fn allocated_size_get(&self) -> Result<u64, Error>

works only when stats are on - but it create performance impact

pub fn thread_allocated_size_get(&self, arena_id: u32) -> Result<u64, Error>

does not seem to work right-now, or we do not understand what it returns
