Struct List 

pub struct List<T> { /* private fields */ }

Owned typed list data independent of presentation policy.

List owns its public model independently from Tree. Its presentation binds this recursive data without coupling either public data API to the other component.

Offsets are supported with List::offset and ListItem::offset. A filter callback is intentionally not part of this API: omit items before construction or mark individual ListItem values hidden instead.

List::new creates the same empty container for every value type. Calls that append an item infer T from that value; an empty List states its type explicitly or through its surrounding context.

Implementations

impl<T> List<T>

pub fn new() -> Self

Creates an empty typed list.

pub fn item(self, item: impl Into<ListItem<T>>) -> Self

Appends one top-level item.

pub fn items<I, N>(self, items: I) -> Self

where I: IntoIterator<Item = N>, N: Into<ListItem<T>>,

Appends top-level items in iteration order.

pub const fn hidden(self, hidden: bool) -> Self

Includes or excludes the complete list.

pub const fn offset(self, start: usize, end: usize) -> Self

Omits start top-level items from the front and end from the back.

pub fn item_nodes(&self) -> &[ListItem<T>]

Returns all owned top-level items before visibility and offset are applied.

Trait Implementations

impl<T: Clone> Clone for List<T>

fn clone(&self) -> List<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for List<T>

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

Formats the value using the given formatter.

impl<T> Default for List<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: PartialEq> PartialEq for List<T>

fn eq(&self, other: &List<T>) -> 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.
