Enum HeightmapError 

pub enum HeightmapError {
    Resolution {
        resolution: u32,
    },
    SampleCount {
        resolution: u32,
    },

}

Why check_heightmap refuses a heightmap.

Variants

Resolution

The resolution leaves no cell.

Fields

resolution: u32

The stated resolution.

SampleCount

The resolution squared does not fit the address space.

Fields

resolution: u32

The stated resolution.

Heights

The number of height samples is not the resolution squared.

Fields

resolution: u32

The stated resolution.

found: usize

The samples stored.

expected: usize

The samples the resolution needs.

HeightRange

A sample is outside 0..=MAX_HEIGHT.

Fields

index: usize

The sample’s place in the array.

row: usize

Its row.

column: usize

Its column.

value: i16

Its value.

Holes

The number of holes is not the number of cells.

Fields

found: usize

The holes stored.

cells: usize

The cells of the heightmap.

Trait Implementations

impl Clone for HeightmapError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HeightmapError

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

Formats the value using the given formatter.

impl Display for HeightmapError

impl Eq for HeightmapError

impl Error for HeightmapError

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 From<HeightmapError> for Error

fn from(e: HeightmapError) -> Self

Converts to this type from the input type.

impl PartialEq for HeightmapError

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

Equality operator ==.

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

Inequality operator !=.
