Interface FsPlugin

lib/fs/plugin.go:27–44

FsPlugin provides filesystem-specific statistics collection.

// FsPlugin provides filesystem-specific statistics collection.
type FsPlugin interface {
	// Name returns the plugin identifier (e.g., "zfs", "devicemapper", "vfs").
	Name() string

	// CanHandle returns true if this plugin handles the given filesystem type.
	CanHandle(fsType string) bool

	// Priority returns the plugin priority (higher = checked first).
	// Allows specific plugins (zfs, btrfs) to override generic (vfs).
	Priority() int

	// GetStats returns filesystem statistics for a partition.
	GetStats(device string, partition PartitionInfo) (*FsStats, error)

	// ProcessMount optionally modifies mount info during processing.
	// Returns (shouldInclude bool, modifiedMount *mount.Info, error).
	ProcessMount(mnt *mount.Info) (bool, *mount.Info, error)
}

// FsCachingPlugin is an optional interface for plugins that want to cache
// stats by a key (e.g., device ID) to avoid redundant stat calls.
