Variants

InvalidCellSize

Cell dimensions must be positive finite values.

Fields

x: f64

Invalid x cell size.

y: f64

Invalid y cell size.

ObserverOutOfBounds

Observer position is outside the DEM grid.

Fields

row: usize

Observer row index.

col: usize

Observer column index.

height: usize

Grid height in rows.

width: usize

Grid width in columns.

InvalidViewshedMaxDistance(f64)

Viewshed maximum distance must be positive and finite, or positive infinity.

InvalidContourInterval(f64)

Contour interval is not a positive, finite number.

ShapeMismatch

Two input grids have different shapes.

Fields

left: &'static str

Name of the first grid.

left_shape: (usize, usize)

Shape of the first grid.

right: &'static str

Name of the second grid.

right_shape: (usize, usize)

Shape of the second grid.

PourPointOutOfBounds

Pour point position is outside the input grid.

Fields

row: usize

Pour point row index.

col: usize

Pour point column index.

height: usize

width: usize

Grid width in columns.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
