Trait hyper_staticfile::vfs::FileOpener

pub trait FileOpener: Send + Sync + 'static {
    type File: IntoFileAccess;
    type Future: Future<Output = Result<FileWithMetadata<Self::File>, Error>> + Send;

    fn open(&self, path: &Path) -> Self::Future;
}

Trait for a simple virtual filesystem layer.

There is only the open operation, hence the name FileOpener. In practice, open must also collect some file metadata. (See the FileWithMetadata struct.)

Required Associated Types

type File: IntoFileAccess

File handle type.

type Future: Future<Output = Result<FileWithMetadata<Self::File>, Error>> + Send

Future type that open returns.

Required Methods

fn open(&self, path: &Path) -> Self::Future

Open a file and return a FileWithMetadata.

It can be assumed the path is already sanitized at this point.

Implementors

impl FileOpener for MemoryFs

type File = Cursor<Bytes>

type Future = Ready<Result<FileWithMetadata<<MemoryFs as FileOpener>::File>, Error>>

impl FileOpener for TokioFileOpener

type File = File

type Future = TokioFileFuture
