Struct PortDecl 

pub struct PortDecl {
    pub key: PortKey,
    pub dir: PortDirection,
    pub kind: PortKind,
    pub capacity: PortCapacity,
    pub ty: Option<TypeDesc>,
    pub label: Option<String>,
    pub view: PortViewDescriptor,
}

Declares a port for a node kind.

Fields

key: PortKey

Stable schema key for this port.

dir: PortDirection

Direction.

kind: PortKind

Kind.

capacity: PortCapacity

Capacity.

ty: Option<TypeDesc>

Optional type descriptor.

label: Option<String>

UI-facing label.

view: PortViewDescriptor

Adapter-facing handle and label presentation metadata.

Implementations

impl PortDecl

pub fn new( key: impl Into<PortKey>, dir: PortDirection, kind: PortKind, capacity: PortCapacity, ) -> Self

Creates a port declaration.

pub fn data_input(key: impl Into<PortKey>) -> Self

Creates a single-capacity data input port.

pub fn data_output(key: impl Into<PortKey>) -> Self

Creates a multi-capacity data output port.

pub fn with_type(self, ty: TypeDesc) -> Self

Sets the port type descriptor.

pub fn with_label(self, label: impl Into<String>) -> Self

Sets the adapter-facing label.

pub fn with_view(self, view: PortViewDescriptor) -> Self

Sets the adapter-facing port view descriptor.

pub fn on_top(self) -> Self

Places this port on the top side.

pub fn on_right(self) -> Self

Places this port on the right side.

pub fn on_bottom(self) -> Self

Places this port on the bottom side.

pub fn on_left(self) -> Self

Places this port on the left side.

pub fn with_view_order(self, order: i32) -> Self

Sets deterministic ordering within the selected side/group.

pub fn with_view_group(self, group: impl Into<String>) -> Self

Groups this port with related handles for adapter presentation.

pub fn with_view_anchor(self, anchor: impl Into<String>) -> Self

Anchors this port to an adapter-owned region such as a field row.

pub fn hidden_handle(self) -> Self

Hides this handle from adapter hit testing without removing the semantic port.

pub fn with_capacity(self, capacity: PortCapacity) -> Self

Sets the capacity.

Trait Implementations

impl Clone for PortDecl

fn clone(&self) -> PortDecl

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PortDecl

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PortDecl

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PortDecl

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
