Enum TilesetError 

#[non_exhaustive]
pub enum TilesetError {
    ImageDecode(String),
    InvalidDimensions(u32, u32, u16, u16),
    EmptyCodepage,
    ZeroTileSize,
    TooManyColumns(u16, u32),
}

Errors that can occur during tileset validation or decoding.

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.

ImageDecode(String)

Image decode failed: the bytes are not a sprite sheet in a format the image crate supports.

InvalidDimensions(u32, u32, u16, u16)

The image dimensions are not evenly divisible by the declared tile size.

EmptyCodepage

The codepage mapping table has zero entries.

ZeroTileSize

tile_width or tile_height is zero.

TooManyColumns(u16, u32)

TilesetBuilder::columns declared more columns than the image actually has at the given tile_width: honoring it would read tile pixels from past the end of the decoded buffer.

Trait Implementations

impl Debug for TilesetError

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

Formats the value using the given formatter.

impl Display for TilesetError

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

Formats the value using the given formatter.

impl Error for TilesetError

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.
