Modules

BorrowedBuf A borrowed buffer of initially uninitialized elements, which is incrementally filled.
BorrowedCursor A writeable view of the unfilled portion of a BorrowedBuf.
Chain Adapter to chain together two readers.
Cursor A Cursor wraps an in-memory buffer and provides it with a Seek implementation.
Custom A user-created allocated error.
CustomOwner Effectively a Box<Custom> without alloc. The Custom holds the call to free this pointer.
Empty Empty ignores any data written via Write, and will always be empty (returning zero bytes) when read via Read.
Error The error type for I/O operations of the [Read][Read], [Write][Write], [Seek][Seek], and associated traits.
IoSlice A buffer type used with Write::write_vectored.
IoSliceMut A buffer type used with Read::read_vectored.
OsFunctions
Repeat A reader which yields one byte over and over and over and over and over and...
SimpleMessage
Sink A writer which will move data into the void.
Take Reader adapter which limits the bytes read from an underlying reader.

IoHandle Marks that a type T can have IO traits such as Seek, Write, etc. automatically implemented for handle types like [Arc][arc] as well.
Seek The Seek trait provides a cursor which can be moved within a stream of bytes.
SizeHint Internal trait used to allow for specialization in Read::size_hint and Iterator::size_hint.
Write A trait for objects which are byte-oriented sinks.
WriteThroughCursor Trait used to allow indirect implementation of Write for Cursor<Self>. Since Cursor is not a foundational type, it is not possible to implement Write for Cursor<T> if Write is defined in libcore and T is in a downstream crate (e.g., liballoc or libstd).

chain
default_write_vectored Default implementation of Write::write_vectored, which is currently used in libstd for file system implementations of similar methods.
empty Creates a value that is always at EOF for reads, and ignores all data written.
repeat Creates an instance of a reader that infinitely repeats one byte.
sink Creates an instance of a writer which will successfully consume all data.
slice_write Non-resizing Write::write implementation for slices. Exported for Cursor<Box<[u8], A>>'s implementation of Write.
slice_write_all Non-resizing Write::write_all implementation for slices. Exported for Cursor<Box<[u8], A>>'s implementation of Write.
slice_write_all_vectored Non-resizing Write::write_all_vectored implementation for slices. Exported for Cursor<Box<[u8], A>>'s implementation of Write.
slice_write_vectored Non-resizing Write::write_vectored implementation for slices. Exported for Cursor<Box<[u8], A>>'s implementation of Write.
stream_len_default The default implementation of Seek::stream_len. This may be desirable in libstd where the default implementation is desirable, but additional work needs to be done before or after.
take

const_error Creates a new I/O error from a known kind of error and a string literal.
