// Package fuse allows the creation of user mode file systems in Go.
//
// A user mode file system must implement the methods in FileSystemInterface
// and be hosted (mounted) by a FileSystemHost.
// Alternatively a user mode file system can use the FileSystemBase struct which
// provides default implementations of the methods in FileSystemInterface.
// A user mode file system is a user mode process that receives file system operations
// from the OS FUSE layer and satisfies them in user mode. A user mode file system
// implements the interface FileSystemInterface either directly or by embedding a
// FileSystemBase struct which provides a default (empty) implementation of all methods
// in FileSystemInterface.
//
// In order to expose the user mode file system to the OS, the file system must be hosted
// (mounted) by a FileSystemHost. The FileSystemHost Mount() method is used for this
// purpose.

// FileSystemInterface is the interface that all file systems must implement.
// The file system will receive an Init() call when it is mounted and a Destroy()
// call when it is unmounted (note that depending on how the file system is
// terminated the file system may not receive the Destroy() call). All other
// operations must return 0 on success or a FUSE error on failure. To return an
// error return the NEGATIVE value of a particular error. For example, to report

// FileSystemInterface is the interface that a user mode interface must implement.

// The file system will receive an Init() call when the file system is created;
// the Init() call will happen prior to receiving any other file system calls.
// Note that there are no guarantees on the exact timing of when Init() is called.
// For example, it cannot be assumed that the file system is mounted at the time
// the Init() call is received.

// The file system will receive a Destroy() call when the file system is destroyed;
// the Destroy() call will always be the last call to be received by the file system.
// Note that depending on how the file system is terminated the file system may not
// receive the Destroy() call. For example, it will not receive the Destroy() call
