    MixedEmptyAndNonEmptyPaths,
    InvalidNode {
        node: usize,
        node_count: usize,
    },

}

Errors returned when constructing an invalid lattice.

Variants

Empty

The lattice has no nodes.

MixedEmptyAndNonEmptyPaths

Empty paths were mixed with non-empty paths.

InvalidNode

An arc endpoint is outside the node range.

Fields

node: usize

Invalid node index.

node_count: usize

Number of nodes in the lattice.

InvalidArcOrder

An arc does not respect topological node order.

Fields

src: usize

Source node index.

dst: usize

Destination node index.

InvalidEndpoint

Start or end node indices are outside the valid range.

Fields

start: usize

Start node index.

end: usize

End node index.

Trait Implementations

impl Clone for LatticeError

fn clone(&self) -> LatticeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LatticeError

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

Formats the value using the given formatter.

impl Display for LatticeError

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

Formats the value using the given formatter.

impl Eq for LatticeError

impl Error for LatticeError

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 LatticeError

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