Enum TileError 

#[non_exhaustive]
pub enum TileError {
    InvalidExtent,
    BufferTooLarge,
    GeometryTooLarge,
    Overflow,
    Conflict(Vec<TileId>),
}

Something the slicer or combiner cannot process. Returned in place of a panic or a silently-wrong result.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidExtent

The per-tile output resolution / tile side (extent) was zero, or extent + buffer was larger than i32::MAX.

BufferTooLarge

The buffer was too large for the tile size: it must be strictly less than half the extent, so geometry near a tile edge spills into at most one neighboring tile per axis.

GeometryTooLarge

A polygon has more than u32::MAX rings or edges, or one of its pieces more than u32::MAX vertices — beyond the u32 indices the slicer keeps.

Overflow

Coordinate arithmetic overflowed i32 — a coordinate or tile lies too close to the limits of the representable range for the given extent/buffer.

Conflict(Vec<TileId>)

While combining tiles, the added tile disagreed with the already-added tiles on a shared border segment (see Mosaic::add). Ids are sorted and unique; the mosaic is left unchanged.

Trait Implementations

impl Eq for TileError

impl Error for TileError

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 TileError

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

Equality operator ==.

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

Inequality operator !=.
