Implementations

impl<C: ChildRecord> Children<C>

pub fn id(&self) -> &str

The address the container is published under.

pub fn children(&self) -> Vec<Listed<C>>

Every child outside the trash, with its place and its state as a read, in order: a child whose record is on its way from the workspace is pending. Show it with ViewCx::arriving.

pub fn child(&self, id: &Id) -> Option<Rc<C::State>>

Child id, listed or in the trash, when its record is here.

pub fn revision(&self) -> u64

Increases whenever a child or the container changed.

pub fn create( &self, fields: Value, group: Option<&Id>, before: Option<&Id>, ) -> Result<Id, ActionError>

Make a child with its first fields (its JSON form, partial) under group, before before, as the window’s person. Its id.

Errors

As the door refuses create.

pub fn delete(&self, id: &Id) -> Result<(), ActionError>

Put child id in the workspace’s trash, as the window’s person.

Errors

As the door refuses delete.

pub fn restore(&self, id: &Id) -> Result<(), ActionError>

Take child id out of the trash, as the window’s person.

Errors

As the door refuses restore.

pub fn move_to( &self, id: &Id, group: Option<&Id>, before: Option<&Id>, ) -> Result<(), ActionError>

Move child id under group, before before, as the window’s person.

Errors

As the door refuses move.

pub fn apply(&self, id: &Id, action: &C::Action) -> Result<(), ActionError>

Apply one of child id’s own actions, as the window’s person.

Errors

As the door refuses it.

pub fn published(&self) -> ResourceSpec

The container published as the door publishes it, for a test.

pub fn invoke_published( &self, action: &EncodedAction, invoker: &ActionInvoker, ) -> Result<ActionOutput, String>

Carry out a published action of the container, as the door does: what an agent invoking it reaches.

Errors

As the door refuses it.

pub fn detached_in( store: RecordStore, app_id: &'static str, me: &str, parent: impl Fn() -> Rc<<C::Parent as Resource>::State> + 'static, ) -> Option<Self>

Children held outside any host, for a tool or a test: in store, which holds the parent’s record, edited as me, who may do anything, the parent read from parent. None when C does not read as a child.

Trait Implementations

impl<C: ChildRecord> Clone for Children<C>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
