Module fs

Prelude: file system

The purpose of this module is to expose common file system operations.

Modules

• prelude
  Prelude for async utilities for use in web applications.
• read
  Reads HTTP/1 Requests and Responses from a AsyncReader.
• write
  Writes HTTP/1 Responses and Requests to a AsyncWrite.

Structs

• File
  A reference to an open file on the filesystem.
• OpenOptions
  Options and flags which can be used to configure how a file is opened.
• ReadToAsync
  Helper struct for read_to_async.

Functions

• read_to_async
  An adaptor between std’s Read and tokio’s AsyncRead traits. This should be used when you have a foreign type which implements read (on a Vec, for example) that returns immediately, because you buffered the actual read with tokio.
• read_to_end
  Reads reader to end into buffer. Also see read_to_end_or_max().
• read_to_end_or_max
  Reads from reader to buffer until it returns zero bytes or max_length is reached. BytesMut::len is used as a starting length of buffer. Note that max_len is a suggestion and will probably be overran.
