Enum RegionDbError 

pub enum RegionDbError {
    Sqlite(Error),
    UnsupportedFormat {
        found: i64,
        supported: i64,
    },
    NotARegionDatabase,
    MissingSpatialIndex,
    Geometry(GeometryError),
    Position(MortonError),
}

Anything that can go wrong opening or querying a region database.

Variants

Sqlite(Error)

The underlying SQLite call failed.

UnsupportedFormat

The file declares a format version this crate does not implement.

Fields

found: i64

Version the file claims.

supported: i64

Highest version this crate understands.

NotARegionDatabase

The file is not a region database at all.

MissingSpatialIndex

The database needs the R-tree candidate path and this SQLite build has no R-tree module.

Geometry(GeometryError)

A geometry blob could not be decoded.

Position(MortonError)

A position could not be placed on the lookup grid.

Trait Implementations

impl Debug for RegionDbError

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

Formats the value using the given formatter.

impl Display for RegionDbError

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

Formats the value using the given formatter.

impl Error for RegionDbError

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.
