Struct numid::example::NumId

pub struct NumId(_);

A numerical id generated with the numid! macro. This struct example is generated with the macro call : numid!(pub struct NumId);.

Methods

impl NumId

pub const INITIAL_VALUE: u64

Constant defined when calling the numid! macro (0 if not defined). The firt id created (with new() or default()) will have value = INITIAL_VALUE + 1.

pub fn new() -> NumId

Increment the current value and create a new id with value = current_value().

pub const fn value(self) -> u64

Get the value of the id.

pub fn current_value() -> u64

Return the value of the last id created (with new() or default()), if no id has been created, return initial_value().

pub const fn initial_value() -> u64

Return INITIAL_VALUE.

pub fn replace_current_value(value: u64) -> bool

Replace the current value by the value parameter if it superior. This condition is necessary for not creating multiple ids with the same value. Return true if the current value has been modified.

pub fn create_lower(value: u64) -> NumId

Create a id with a precised value, don't increment the current value. The value must be inferior or equal as INITIAL_VALUE for not interfering with the id system.

Panics

panic if value > INITIAL_VALUE
