Enum MapError 

pub enum MapError {
    MapTileCacheError(MapTileCacheError),
    ZoomFitError(ZoomFitError),
    MapTileCropError,
    MapCoordinateError,
    NoOverlapError,
    NoGridCoordinatesForRegion(RegionName),
    RegionNameToGridCoordinateCacheError(CacheError),

}

represents errors that can occur while creating a map

Variants

MapTileCacheError(MapTileCacheError)

an error in the map tile cache

ZoomFitError(ZoomFitError)

an error occurred when trying to calculate the zoom level that fits the map grid rectangle into the output image

MapTileCropError

failed to crop a map tile to the required size

MapCoordinateError

failed to calculate pixel coordinates where we want to place a map tile crop

NoOverlapError

no overlap between map tile we fetched and output map (should not happen)

NoGridCoordinatesForRegion(RegionName)

no grid coordinates were returned for one of the region names in the USB Notecard

RegionNameToGridCoordinateCacheError(CacheError)

error in region name to grid coordinate cache

SplineError(SplineError)

error calculating spline

Trait Implementations

impl Debug for MapError

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

Formats the value using the given formatter.

impl Display for MapError

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

Formats the value using the given formatter.

impl Error for MapError

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.
