Enum MobileRegionError 

pub enum MobileRegionError {
    DatabaseUnavailable,
    NotARegionDatabase,
    UnsupportedFormat,
    MissingSpatialIndex,
    Corrupt,
    InvalidPosition,
    PositionTooCoarse,
    InvalidRegionCode,
}

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

Variants

DatabaseUnavailable

The database file could not be opened or read.

NotARegionDatabase

The file is not a region database at all.

UnsupportedFormat

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

MissingSpatialIndex

The database needs SQLite’s R-tree module and this build has none.

Corrupt

The database opened but its contents could not be decoded.

InvalidPosition

The position is not a place: a non-finite or out-of-range coordinate, or an undecodable location cell.

PositionTooCoarse

The position is real but too uncertain to propose from. The answer is a better source, not a wider guess.

InvalidRegionCode

A configured region string or default-region code could not be read.

Implementations

impl MobileRegionError

pub const fn summary_key(self) -> &'static str

Stable localization key. Rust prose is never shown directly in the UI.

pub const fn diagnostic_code(self) -> &'static str

Redacted diagnostic code suitable for logs and support bundles.

Trait Implementations

impl Clone for MobileRegionError

fn clone(&self) -> MobileRegionError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<UT> ConvertError<UT> for MobileRegionError

fn try_convert_unexpected_callback_error( e: UnexpectedUniFFICallbackError, ) -> Result<Self>

impl Error for MobileRegionError

fn source(&self) -> Option<&(dyn Error + 'static)>
