Struct Weight 

pub struct Weight(/* private fields */);

Snap ranking weight. Higher values indicate greater hydrological dominance; adapters typically populate this with upstream drainage area in km² or cell count. Snap-aware engines rank snap candidates by descending weight, using mainstem status and distance as tie-breakers.

Invariant: the wrapped value is always finite and non-negative.

Eq is intentionally not derived for the same reason as AreaKm2.

Implementations

impl Weight

pub fn new(raw: f32) -> Result<Self, MeasureError>

Construct a Weight from a raw f32.

Errors

Condition	Error variant
raw is NaN or infinite	MeasureError::NonFiniteValue
raw < 0.0	MeasureError::NegativeValue

pub fn get(self) -> f32

Return the underlying f32 value.

Trait Implementations

impl Clone for Weight

fn clone(&self) -> Weight

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Weight

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

Formats the value using the given formatter.

impl PartialEq for Weight

fn eq(&self, other: &Weight) -> 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 PartialOrd for Weight

fn partial_cmp(&self, other: &Weight) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
