Struct Creations 

pub struct Creations<Item> { /* private fields */ }

One ordered creation batch.

The batch is the all-or-none unit for runtime route preparation. After routing succeeds, each child still settles independently in this declared order.

Implementations

impl<Item> Creations<Item>

pub const fn empty() -> Self

Construct an empty creation batch.

pub fn one(item: Item) -> Self

pub fn and(self, item: Item) -> Self

pub fn map<Mapped>(self, map: impl FnMut(Item) -> Mapped) -> Creations<Mapped>

Transform every item while preserving declared order and cardinality.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn iter(&self) -> Iter<'_, Item>
