Struct Tier 

pub struct Tier { /* private fields */ }

A horizontal band of nodes in the diagram, optionally wrapped in a container.

Each tier has a unique ID, an optional label, a layout hint, and either a list of nodes or a container (or both).

Implementations

impl Tier

pub fn new(id: NodeId, nodes: Vec<Node>) -> Self

Creates a new tier with nodes.

pub fn with_container(id: NodeId, container: Container) -> Self

Creates a new tier with a container.

pub fn id(&self) -> &NodeId

Returns the tier’s unique identifier.

pub fn label(&self) -> Option<&str>

Returns the optional tier heading label.

pub fn set_label(&mut self, label: &str)

Sets the tier heading label.

pub fn layout(&self) -> &TierLayout

Returns the layout configuration.

pub fn set_layout(&mut self, layout: TierLayout)

Sets the layout configuration.

pub fn nodes(&self) -> &[Node]

Returns the nodes in this tier.

pub fn container(&self) -> Option<&Container>

Returns the optional container.

pub fn is_empty(&self) -> bool

Returns true if this tier has neither nodes nor a container.

Trait Implementations

impl Clone for Tier

fn clone(&self) -> Tier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Tier

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Tier

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Tier

fn eq(&self, other: &Tier) -> 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.

impl Serialize for Tier

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
