Modules§
Macros§
- const_
error Experimental - Creates a new I/O error from a known kind of error and a string literal.
Structs§
- Borrowed
Buf Experimental - A borrowed buffer of initially uninitialized elements, which is incrementally filled.
- Borrowed
Cursor Experimental - A writeable view of the unfilled portion of a
BorrowedBuf. - Chain
Experimental - Adapter to chain together two readers.
- Cursor
Experimental - A
Cursorwraps an in-memory buffer and provides it with aSeekimplementation. - Empty
Experimental Emptyignores any data written viaWrite, and will always be empty (returning zero bytes) when read viaRead.- Error
Experimental - The error type for I/O operations of the
Read,Write,Seek, and associated traits. - IoSlice
Experimental - A buffer type used with
Write::write_vectored. - IoSlice
Mut Experimental - A buffer type used with
Read::read_vectored. - Repeat
Experimental - A reader which yields one byte over and over and over and over and over and…
- Simple
Message 👻Experimental - Sink
Experimental - A writer which will move data into the void.
- Take
Experimental - Reader adapter which limits the bytes read from an underlying reader.
Enums§
- Error
Kind Experimental - A list specifying general categories of I/O error.
- Seek
From Experimental - Enumeration of possible methods to seek within an I/O object.
Traits§
- Seek
Experimental - The
Seektrait provides a cursor which can be moved within a stream of bytes. - Write
Experimental - A trait for objects which are byte-oriented sinks.
Functions§
- empty
Experimental - Creates a value that is always at EOF for reads, and ignores all data written.
- repeat
Experimental - Creates an instance of a reader that infinitely repeats one byte.
- sink
Experimental - Creates an instance of a writer which will successfully consume all data.
Type Aliases§
- RawOs
Error Experimental - The type of raw OS error codes.
- Result
Experimental - A specialized
Resulttype for I/O operations.
