Struct Handle 

pub struct Handle { /* private fields */ }

A simple handle factory for incrementing sequences of numbers.

Implementations

impl Handle

pub fn new(first: u32) -> Handle

Creates a new handle factory, that starts with the supplied number

pub fn next(&mut self) -> u32

Returns the next handle to be issued, internally incrementing each time so the handle is always different until it wraps back to the start.

pub fn peek_next(&self) -> u32

Peek the next value of the handle, without incrementing.

pub fn set_next(&mut self, next: u32)

Set the next handle value manually.

pub fn reset(&mut self)

Resets the handle to its initial state
