Enum TrailError 

pub enum TrailError {
    Discontinuous {
        at: u32,
    },
    Empty(Empty),
    Overflow(Overflow),
}

How drawing a trail refuses.

Variants

Discontinuous

The edges offered are not one walk.

Fields

at: u32

The position of the first edge that does not start where the edge before it ended, counted from the walk’s first edge.

Empty(Empty)

No edge was offered.

Overflow(Overflow)

More edges were offered than the trail admits.

impl Eq for TrailError

impl Error for TrailError

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
