Enum ImageFormatHint

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

A best effort representation for image formats.

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.

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.

impl From<&Path> for ImageFormatHint

fn from(path: &Path) -> ImageFormatHint

Converts to this type from the input type.

impl From<ImageFormat> for ImageFormatHint

fn from(format: ImageFormat) -> ImageFormatHint

Converts to this type from the input type.

impl PartialEq for ImageFormatHint

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
