Enum WorldError 

pub enum WorldError {
    ColumnLengths,
    PositionOutOfRange {
        lef: usize,
        pos: Position,
        n_sites: usize,
    },
    LegsCrossed {
        lef: usize,
        left: Position,
        right: Position,
    },

    },
    CapturedOffCtcf {
        lef: usize,
        pos: Position,
    },

        lef: usize,
        pos: Position,
        facing: Direction,
    },
}

Why a LEF state isn’t valid in a world. lef is the LEF’s id (its row).

Variants

ColumnLengths

The columns of a LefStates have different lengths.

PositionOutOfRange

Fields

lef: usize

pos: Position

n_sites: usize

LegsCrossed

The left leg must not be to the right of the right leg.

Fields

lef: usize

left: Position

right: Position

SiteOccupied

Another leg already sits there. A LEF’s own two legs may share a site (as right after it’s placed); two LEFs may not.

Fields

lef: usize

pos: Position

CapturedOffCtcf

A captured leg must sit on a CTCF…

Fields

lef: usize

pos: Position

CapturedWrongSide

…that captures from the side it arrived from. Legs only step forward, so they arrive from the side opposite their facing: a left-facing leg can only be captured by a CTCF that captures from the right, and a right-facing leg by one that captures from the left.

Fields

lef: usize

pos: Position

facing: Direction

Trait Implementations

impl Clone for WorldError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WorldError

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

Formats the value using the given formatter.

impl Display for WorldError

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

Formats the value using the given formatter.

impl Error for WorldError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for WorldError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

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

Inequality operator !=.
