Expand description

Allows storing files to a file storage backend.

Required Methods§

source

fn upload<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, path: &'life1 Path, contents: Vec<u8>, mime_type: &'life2 str ) -> Pin<Box<dyn Future<Output = Result<(), UtilError>> + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Upload a file that’s in memory to a path.

source

fn upload_stream<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, path: &'life1 Path, contents: Pin<Box<dyn Stream<Item = Result<Bytes, Error>>>>, mime_type: &'life2 str ) -> Pin<Box<dyn Future<Output = Result<(), UtilError>> + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Upload a file without loading the whole file to memory

source

fn download<'life0, 'life1, 'async_trait>( &'life0 self, path: &'life1 Path ) -> Pin<Box<dyn Future<Output = Result<Vec<u8>, UtilError>> + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Download a file to memory.

source

fn download_stream<'life0, 'life1, 'async_trait>( &'life0 self, path: &'life1 Path ) -> Pin<Box<dyn Future<Output = Result<Box<dyn Stream<Item = Result<Bytes, Error>>>, UtilError>> + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Download a file without loading the whole file to memory.

source

fn get_direct_download_url<'life0, 'life1, 'async_trait>( &'life0 self, path: &'life1 Path ) -> Pin<Box<dyn Future<Output = Result<String, UtilError>> + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Get a url that can be used to download the file without authentication for a while. In most cases you probably want to use get_download_url() instead.

source

fn delete<'life0, 'life1, 'async_trait>( &'life0 self, path: &'life1 Path ) -> Pin<Box<dyn Future<Output = Result<(), UtilError>> + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Delete a file.

source

fn get_cache_files_folder_path(&self) -> Result<&Path, UtilError>

This function returns a path to a folder where downloaded files can be cached.

Provided Methods§

source

fn get_download_url( &self, path: &Path, app_conf: &ApplicationConfiguration ) -> String

Get a url for a file in FileStore that can be used to access the resource.

source

fn fetch_file_content_or_use_filesystem_cache<'life0, 'life1, 'async_trait>( &'life0 self, file_path: &'life1 Path ) -> Pin<Box<dyn Future<Output = Result<Vec<u8>, UtilError>> + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,
