Enum image::error::ImageFormatHint

source · [−]

#[non_exhaustive]
pub enum ImageFormatHint {
    Exact(ImageFormat),

    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.
