Methods

impl GenericMetadata

pub fn dimensions(&self) -> Dimensions

Returns image dimensions from the contained metadata.

pub fn mime_type(&self) -> &'static str

Returns a MIME type string for the image type of the contained metadata.

pub fn into<T: MetadataMarker>(self) -> Result<T::Metadata, GenericMetadata>

Attemts to convert this value to the specific metadata type by value.

This method is needed only to provide a convenient syntax and it is not necessary because one may just match on the GenericMetadata value.

pub fn as_ref<T: MetadataMarker>(&self) -> Option<&T::Metadata>

Attempts to convert this value to the sepcific metadata type by reference.

This method is needed only to provide a convenient syntax and it is not necessary because one may just match on the GenericMetadata value.
