Enum PolylineError 

pub enum PolylineError {
    InvalidCharacter {
        character: char,
        position: usize,
    },
    TruncatedData,
    CoordinateOverflow,
    InvalidPrecision(u8),
    EmptyInput,
    InvalidCoordinate(String),
}

Errors that can occur during polyline encoding or decoding operations.

These errors provide detailed information about what went wrong during polyline processing, including specific locations for parsing errors and descriptive messages for coordinate validation failures.

Variants

InvalidCharacter

Invalid character found in polyline string.

Polyline strings must contain only ASCII characters in the range 63-126 (‘?’ to ‘~’). This error includes the invalid character and its position in the string.

Fields

character: char

position: usize

TruncatedData

Truncated or malformed polyline data.

Occurs when the polyline string ends unexpectedly, such as having a latitude delta without a corresponding longitude delta, or when the variable-length encoding is incomplete.

CoordinateOverflow

Coordinate value overflow during encoding or decoding.

Happens when coordinate calculations exceed the range of 64-bit integers, typically with very high precision values or extreme coordinate differences.

InvalidPrecision(u8)

Invalid precision value.

Precision must be between 1 and 11 inclusive. Higher precision values provide more accuracy but may cause overflow with large coordinate values.

EmptyInput

Empty input where coordinates were expected.

Currently unused - empty inputs are handled gracefully by returning empty results rather than errors.

InvalidCoordinate(String)

Invalid coordinate value.

Occurs when coordinates are NaN, infinite, or outside reasonable geographic bounds (±180° longitude, ±90° latitude).

Trait Implementations

impl Clone for PolylineError

fn clone(&self) -> PolylineError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PolylineError

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

Formats the value using the given formatter.

impl Display for PolylineError

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

Formats the value using the given formatter.

impl Error for PolylineError

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.

impl PartialEq for PolylineError

fn eq(&self, other: &PolylineError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
