Struct CreationSequence 

pub struct CreationSequence { /* private fields */ }

Checked source of IDs that are not reused within one child occurrence.

Implementations

impl CreationSequence

pub const fn new() -> Self

Begin a fresh sequence for one child occurrence.

pub fn issue(&mut self) -> Option<CreationId>

Issue the next ID, or return absence after the finite sequence is exhausted. Exhaustion leaves the sequence unchanged.

Trait Implementations

impl Debug for CreationSequence

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CreationSequence

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for CreationSequence

fn eq(&self, other: &CreationSequence) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
