Types ¶

type Disk ¶

type Disk struct {
	Name                   string                  `json:"name"`

	StorageController      block.StorageController `json:"storage_controller"`
	UUID                   string                  `json:"uuid"`    // This would be volume UUID on macOS, UUID on linux, empty on Windows
	PtUUID                 string                  `json:"pt_uuid"` // This would be volume PtUUID on macOS, PartUUID on linux, empty on Windows
	BusPath                string                  `json:"bus_path"`
	FileSystemInfo         FileSystemInfo          `json:"file_system_info"`
	NUMANodeID             int                     `json:"numa_node_id"`
	Vendor                 string                  `json:"vendor"`
	Model                  string                  `json:"model"`

	Partitions             []*Partition            `json:"partitions"`
}

Disk describes a single disk drive on the host system. Disk drives provide raw block storage resources.

type FileSystemInfo ¶

type FileSystemInfo struct {
	Type       string `json:"type"`
	IsReadOnly bool   `json:"read_only"`
	MountPoint string `json:"mount_point"`
}

type Info ¶

type Info interface {
	GetDisks() []*Disk
	GetPartitions() []*Partition
	GetDiskByDevPath(name string) *Disk
	GetPartitionByDevPath(disk, part string) *Partition
	GetFileSystemInfoByDevPath(dname string) *FileSystemInfo
}

Info describes all disk drives and partitions in the host system.

func New ¶

func New() (Info, error)

New returns a pointer to an Info implementation that describes the block storage resources of the host system.

type Partition ¶

type Partition struct {
	Disk              *Disk                   `json:"-"`
	Name              string                  `json:"name"`
	Label             string                  `json:"label"`
	SizeBytes         uint64                  `json:"size_bytes"`
	UUID              string                  `json:"uuid"`    // This would be volume UUID on macOS, PartUUID on linux, empty on Windows
	FsUUID            string                  `json:"fs_uuid"` // This would be filesystem UUID on macOS and linux, empty on Windows
	PartType          string                  `json:"part_type"`
	DriveType         block.DriveType         `json:"drive_type"`
	StorageController block.StorageController `json:"storage_controller"`
	FileSystemInfo    FileSystemInfo          `json:"file_system_info"`
}

Partition describes a logical division of a Disk.

type UUIDType ¶

type UUIDType string

const (
	FsType = "TYPE"

	PartUUID UUIDType = "PARTUUID"
	PTUUID   UUIDType = "PTUUID"
	UUID     UUIDType = "UUID"
)

borrowed from https://github.com/jaypipes/ghw/blob/master/pkg/block/block_linux.go * two function are changed with introducing context * 1. partitionInfo() * 2. openProcMounts()
