Enum FlowError 

pub enum FlowError {
    OutOfRange {
        arc: usize,
    },
    OutOfBounds {
        arc: usize,
    },
    Unbalanced,
    TooLarge,
}

Why a problem was not solved.

Variants

OutOfRange

An arc names a node past the count.

Fields

arc: usize

OutOfBounds

An arc’s capacity is negative or past FLOW_LIMIT, or its cost past COST_LIMIT.

Fields

arc: usize

Unbalanced

The supplies do not sum to zero, or their sizes sum past FLOW_LIMIT.

TooLarge

More than 2³¹ nodes or arcs.

Trait Implementations

impl Clone for FlowError

fn clone(&self) -> FlowError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FlowError

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

Formats the value using the given formatter.

impl PartialEq for FlowError

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