Struct SnapTarget 

pub struct SnapTarget { /* private fields */ }

A candidate location to which a pour point may be snapped.

Each SnapTarget belongs to exactly one drainage unit and carries a proportional Weight used when multiple targets compete within the same unit.

All fields are validated at construction time via their primitive newtypes; SnapTarget itself performs no additional validation.

Implementations

impl SnapTarget

pub fn new( id: SnapId, unit_id: UnitId, weight: Weight, stem_role: Option<StemRole>, bbox: Option<BoundingBox>, geometry: WkbGeometry, ) -> Self

Construct a SnapTarget from its constituent validated fields.

All arguments are already domain-typed, so no further validation is performed here — invalid states are unrepresentable by construction.

pub fn id(&self) -> SnapId

Return the snap target’s unique identifier.

pub fn unit_id(&self) -> UnitId

Return the identifier of the drainage unit this target belongs to.

pub fn weight(&self) -> Weight

Return the proportional weight used for allocation across competing targets.

pub fn stem_role(&self) -> Option<StemRole>

Return the optional stem role for this target.

pub fn bbox(&self) -> Option<&BoundingBox>

Return a reference to the optional axis-aligned bounding box.

pub fn geometry(&self) -> &WkbGeometry

Return a reference to the WKB geometry of this snap target (typically a linestring or point).

Trait Implementations

impl Clone for SnapTarget

fn clone(&self) -> SnapTarget

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SnapTarget

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

Formats the value using the given formatter.

impl HasUnitId for SnapTarget

fn unit_id(&self) -> UnitId

Return the unit identifier.

impl PartialEq for SnapTarget

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