Struct ServeFile

pub struct ServeFile(/* private fields */);

Available on crate feature fs only.

Service that serves a file.

Implementations

impl ServeFile

pub fn new<P: AsRef<Path>>(path: P) -> Self

Create a new ServeFile.

The Content-Type will be guessed from the file extension.

pub fn new_with_mime<P: AsRef<Path>>(path: P, mime: &Mime) -> Self

Create a new ServeFile with a specific mime type.

Panics

Will panic if the mime type isn’t a valid header value.

pub fn precompressed_gzip(self) -> Self

Informs the service that it should also look for a precompressed gzip version of the file.

If the client has an Accept-Encoding header that allows the gzip encoding, the file foo.txt.gz will be served instead of foo.txt. If the precompressed file is not available, or the client doesn’t support it, the uncompressed version will be served instead. Both the precompressed version and the uncompressed version are expected to be present in the same directory. Different precompressed variants can be combined.

pub fn precompressed_br(self) -> Self

Informs the service that it should also look for a precompressed brotli version of the file.

If the client has an Accept-Encoding header that allows the brotli encoding, the file foo.txt.br will be served instead of foo.txt. If the precompressed file is not available, or the client doesn’t support it, the uncompressed version will be served instead. Both the precompressed version and the uncompressed version are expected to be present in the same directory. Different precompressed variants can be combined.

pub fn precompressed_deflate(self) -> Self

Informs the service that it should also look for a precompressed deflate version of the file.

If the client has an Accept-Encoding header that allows the deflate encoding, the file foo.txt.zz will be served instead of foo.txt. If the precompressed file is not available, or the client doesn’t support it, the uncompressed version will be served instead. Both the precompressed version and the uncompressed version are expected to be present in the same directory. Different precompressed variants can be combined.

pub fn precompressed_zstd(self) -> Self

Informs the service that it should also look for a precompressed zstd version of the file.

If the client has an Accept-Encoding header that allows the zstd encoding, the file foo.txt.zst will be served instead of foo.txt. If the precompressed file is not available, or the client doesn’t support it, the uncompressed version will be served instead. Both the precompressed version and the uncompressed version are expected to be present in the same directory. Different precompressed variants can be combined.

pub fn with_buf_chunk_size(self, chunk_size: usize) -> Self

Set a specific read buffer chunk size.

The default capacity is 64kb.

pub fn try_call<ReqBody>( &mut self, req: Request<ReqBody>, ) -> ResponseFuture<ReqBody>

where ReqBody: Send + 'static,

Call the service and get a future that contains any std::io::Error that might have happened.

See ServeDir::try_call for more details.
