Functions ¶
func Describe ¶
func Describe(err error) screenwire.Diagnostic
Describe preserves errors.As/Is evidence through cleanup errors.Join without formatting the underlying error (which may contain device-specific text).
Types ¶
type Trace ¶
type Trace struct {
// contains filtered or unexported fields
}
Trace observes one serialized panel owner. It retains no pixels, errors, tokens or transaction identities. Snapshot never calls hardware or the clock.
func (*Trace) Snapshot ¶
func (t *Trace) Snapshot() screenwire.PanelStatus
func (*Trace) WrapIO ¶
WrapIO preserves every pin/write/delay callback and forwards each BUSY read exactly once. Only reads inside existing driver waits are counted; a zero LOW count says nothing about the pin during command delays or visible pixels.
