Struct syslog_rs::unsafe_cell::UnsafeReadOnlyCell

pub struct UnsafeReadOnlyCell<T: Send> { /* private fields */ }

Implementations

impl<T: Send> UnsafeReadOnlyCell<T>

pub unsafe fn new_uninitialized(title: &'static str) -> UnsafeReadOnlyCell<T>

Creates new unititialized Cell. A contained type must implement Send and maybe Sync

Arguments

• title - is a label which used to help in panic diagnostic.

Returns

• A UnsafeReadOnlyCell of type . Never panics

Example

#[macro_use] extern crate lazy_static;
use syslog_rs::UnsafeReadOnlyCell;
struct Syslog{}
lazy_static! {
    static ref SYSLOG: UnsafeReadOnlyCell<Syslog> = 
        unsafe { UnsafeReadOnlyCell::new_uninitialized("a_label") };
}

pub unsafe fn init(&self, init: T)

Initializes the intance with provided data in init and locks the instance from modification. This function is unsafe and involves atomic operation.

Return

Nothing, but will panic on attempt to call this function again.

pub fn is_init(&self) -> bool

Returns the status of instance.

Return

True - is locked or false.
