Enum PlannerError 

pub enum PlannerError {
    ZeroDimension {
        width: u32,
        height: u32,
    },
    ZeroTileSize(u32),
    OverlapTooLarge {
        overlap: u32,
        tile_size: u32,
    },
    DimensionOverflow {
        width: u32,
        height: u32,
    },
}

Errors that can occur when constructing a PyramidPlanner.

These represent invalid configurations that would lead to undefined behaviour during pyramid generation – for example, zero-sized images or an overlap that equals or exceeds the tile size. Catching them at planner-construction time keeps the rest of the pipeline free of defensive checks.

Trait Implementations

impl Debug for PlannerError

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

Formats the value using the given formatter.

impl Display for PlannerError

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

Formats the value using the given formatter.

impl Error for PlannerError

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>)
