Implementations

impl GoogleCloudFileStore

pub async fn new(bucket_name: String) -> UtilResult<Self>

Creates a Google Cloud file store using ADC-backed SDK clients.

fn bucket_resource_name(&self) -> String

Converts a raw bucket id into the GCS API resource name format.

fn build_credentials_and_signer() -> UtilResult<(Option<Credentials>, Signer)>

Builds Google Cloud credentials while preserving the legacy cloud-storage crate’s support for JSON credentials supplied directly in an environment variable.

fn credentials_json_from_env() -> UtilResult<Option<Value>>

fn map_init_error<E: Error + Send + Sync + 'static>(error: E) -> UtilError

Maps SDK initialization errors into the cloud storage util error.

Trait Implementations

impl FileStore for GoogleCloudFileStore

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

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

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

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

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

Download a file to memory.

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

where Self: 'async_trait, 'life0: 'async_trait, 'life1: '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.

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

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

Delete a file.

fn upload_stream<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, path: &'life1 Path, contents: GenericPayload, mime_type: &'life2 str, ) -> Pin<Box<dyn Future<Output = UtilResult<()>> + 'async_trait>>

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

Upload a file without loading the whole file to memory

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

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

Download a file without loading the whole file to memory.

fn get_cache_files_folder_path(&self) -> UtilResult<&Path>

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

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.

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

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