Enum Layer 

#[non_exhaustive]
pub enum Layer {
    Tier(Tier),
    Connector(Connector),
    FlowLabels(FlowLabels),
}

A single visual element in the diagram’s layer stack.

Layers are rendered in order from top to bottom. Each layer is exactly one of: a tier (horizontal band of nodes), a connector (visual link between tiers), or flow labels (directional arrows).

In YAML, each layer is a map with a single key identifying the variant:

- tier:
    id: main
    nodes: [...]
- connector:
    style: line
- flow_labels:
    items: [...]

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Tier(Tier)

A horizontal band of nodes.

Connector(Connector)

A visual connector between adjacent tiers.

FlowLabels(FlowLabels)

Directional labels between tiers.

Trait Implementations

impl Clone for Layer

fn clone(&self) -> Layer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Layer

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Layer

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Layer

fn eq(&self, other: &Layer) -> 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 Layer

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
