Enum NavError 

pub enum NavError {
    EmptyRegion,
    BadIndex,
    DegeneratePolygon,
    NoWalkableArea,
    InvalidConfig,
}

A navigation setup or query refused to build.

Variants

EmptyRegion

The bake region is empty or inverted.

BadIndex

DegeneratePolygon

A polygon had fewer than three vertices.

NoWalkableArea

The region held no walkable cell after erosion.

InvalidConfig

impl Eq for NavError

impl Error for NavError

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.
