Types ¶

type SimpleExtendedAttributes ¶

type SimpleExtendedAttributes struct {
	// contains filtered or unexported fields
}

SimpleExtendedAttributes implements extended attributes using a map of names to values.

SimpleExtendedAttributes calls vfs.CheckXattrPermissions, so callers are not required to do so.

func (*SimpleExtendedAttributes) GetXattr ¶

func (x *SimpleExtendedAttributes) GetXattr(creds *auth.Credentials, mode linux.FileMode, kuid auth.KUID, opts *vfs.GetXattrOptions) (string, error)

GetXattr returns the value at 'name'.

func (*SimpleExtendedAttributes) ListXattr ¶

func (x *SimpleExtendedAttributes) ListXattr(creds *auth.Credentials, size uint64) ([]string, error)

ListXattr returns all names in xattrs.

func (*SimpleExtendedAttributes) RemoveXattr ¶

func (x *SimpleExtendedAttributes) RemoveXattr(creds *auth.Credentials, mode linux.FileMode, kuid auth.KUID, name string) error

RemoveXattr removes the xattr at 'name'.

func (*SimpleExtendedAttributes) SetXattr ¶

func (x *SimpleExtendedAttributes) SetXattr(creds *auth.Credentials, mode linux.FileMode, kuid auth.KUID, kgid auth.KGID, opts *vfs.SetXattrOptions) error

SetXattr sets 'value' at 'name'.
