impl VariantProcessor for ImageProcessor

type ProcessingOptions = ImageOptions

fn get_valid_variants_for_content_type(_content_type: &str) -> Vec<FileVariant>

Returns a list of valid variants for a given content type If there are no valid variants for the content type, return an empty list

fn get_content_type_for_variant( file: &FileDetails, variant: &FileVariant, ) -> String

Returns the content type for a given variant

fn get_options_for_variant( file: &FileDetails, variant: &FileVariant, ) -> Result<ImageOptions, DynError>

Returns the processing options for a given variant If there are no options for this variant, return an error

fn process<'life0, 'life1, 'life2, 'async_trait>( origin_file_path: &'life0 str, output_file_path: &'life1 str, options: &'life2 ImageOptions, ) -> Pin<Box<dyn Future<Output = Result<String, DynError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Processes the origin file and saves the output to the output_file_path based on the passed options Returns the content type of the processed file or the original content type if no processing was done

fn create_variant<'life0, 'life1, 'async_trait>( file: &'life0 FileDetails, variant: &'life1 FileVariant, file_path: PathBuf, ) -> Pin<Box<dyn Future<Output = Result<String, DynError>> + Send + 'async_trait>>

where Self: Send + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Creates a variant for the given file If there are no options for this variant, return with the original content type
