Crate orengine_utils 

This crate provides some useful utilities.

• The hints module provides hints to the compiler that affects how code should be emitted or optimized.
• The backoff module provides the Backoff structure.
• The cache_padded module provides cache-padded atomics types and the [CachePadded] wrapper.
• The light_arc module provides the LightArc type.
• The OrengineInstant that is a monotone clock that weights 8 bytes on Unix-like systems.
• The ArrayQueue that is an array-based queue implementation.
• The VecQueue that is a vector-based queue implementation.
• The NumberKeyMap that is a compact open-addressing map specialized for usize keys optimized for zero-misses and so optimized for 99+% reading operations.
• The numa module provides sufficient utilities for working with NUMA nodes.
• Configuration macros that are used to right compile the program based on the target platform such as config_target_pointer_width_64, config_target_pointer_width_32, and config_target_pointer_width_16.

Re-exports

pub use number_key_map::NumberKeyMap;

Modules

backoff

This module provides a Backoff that can be used to busy-wait with preemptive yield when it is necessary.

cache_padded

Provides cache-padded atomic types.

hints

Hints to the compiler that affects how code should be emitted or optimized.

light_arc

This module provides LightArc.

numa

Provides utilities for working with NUMA (Non-Uniform Memory Access) nodes.

number_key_map

This module provides the NumberKeyMap struct.

Macros

config_target_pointer_width_16

Generates code only compiled when the target pointer width is 16 bits.

config_target_pointer_width_32

Generates code only compiled when the target pointer width is 32 bits.

config_target_pointer_width_64

Generates code only compiled when the target pointer width is 64 bits.

Structs

ArrayBuffer

ArrayBuffer is a fixed-sized array-based buffer.

ArrayQueue

ArrayQueue is a queue, but it uses an array on a stack and can’t be resized.

OrengineInstant

A monotone clock. It can be converted to/from std::time::Instant.

VecQueue

A queue that uses a vector to store the elements.

Functions

clear_with

This function is like drain for the whole Vec, but faster.
