Module generic 

🔬This is a nightly-only experimental API. (alloc_io #154046)

Constants

IN_MEMORY 🔒 Experimental

Readers and writers with their entire contents have the highest priority.

UNBUFFERED 🔒 Experimental

Unbuffered readers and writers have the lowest priority.

Traits

BufferedReaderSpec 🔒 Experimental

Specialization of the read-write loop in generic_copy that reuses the internal buffer of a BufReader. If there’s no buffer then the writer side should be used instead.

BufferedWriterSpec 🔒 Experimental

Specialization of the read-write loop in generic_copy that either uses a stack buffer or reuses the internal buffer of a BufWriter.

Functions

generic_copy 🔒 Experimental

The userspace read-write-loop implementation of io::copy that is used when OS-specific specializations for copy offloading are not available or not applicable.

stack_buffer_copy 🔒 Experimental

Copies from reader to writer using a stack-allocated buffer (a fixed sized array).

Type Aliases

BufferPriority 🔒 Experimental

This is used by generic_copy to decide whether to use BufferedReaderSpec::copy_to or BufferedWriterSpec::copy_from.
