Expand description

A minimal base trait for array I/O. Defines operations common to all kinds of random-access devices that fit the “array” concept, including normal files, block devices, and in-memory buffers.

This is a base trait that ReadAt, WriteAt, and EditAt all share.

Required Methods

Return the Metadata for the array. This is similar to std::fs::File::metadata, though it returns fewer fields since the underlying device may not be an actual filesystem inode.

Announce the expected access pattern of the data at the given offset.

This is purely a performance hint and has no semantic effect.
