#[non_exhaustive]
pub enum ImageFormatHint { Exact(ImageFormat), Name(String), PathExtension(PathBuf), Unknown, }
Expand description

A best effort representation for image formats.

Variants (Non-exhaustive)§

This enum is marked as 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.
§

Exact(ImageFormat)

The format is known exactly.

§

Name(String)

The format can be identified by a name.

§

PathExtension(PathBuf)

A common path extension for the format is known.

§

Unknown

The format is not known or could not be determined.
