Struct UpdateState 

pub struct UpdateState {
    pub target_application: Option<PathBuf>,
    pub temporary_application: Option<PathBuf>,
    pub trace_context: Option<HashMap<String, String>>,
    pub phase: UpdatePhase,
}

The serializable state which is threaded through the three phases of an update by relaunching the application with the RESUME_FLAG followed by this value as JSON.

Fields

target_application: Option<PathBuf>

The path to the application binary which is being updated.

temporary_application: Option<PathBuf>

The path to the temporary binary which the new release was downloaded to.

trace_context: Option<HashMap<String, String>>

A trace-context propagation carrier (e.g. the W3C traceparent / tracestate headers) captured from the phase that relaunched the application. With the opentelemetry feature it lets the phases of an update — which each run in a separate process — continue a single distributed trace. The field is always part of the wire format (so states stay compatible across feature configurations) but is only populated and consumed when that feature is enabled.

phase: UpdatePhase

The phase of the update process which this state represents.

Implementations

impl UpdateState

pub fn for_phase(&self, phase: UpdatePhase) -> Self

Produce a copy of this state advanced to the provided UpdatePhase, preserving the application paths and any captured trace context.

Trait Implementations

impl Clone for UpdateState

fn clone(&self) -> UpdateState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UpdateState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for UpdateState

fn default() -> UpdateState

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for UpdateState

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for UpdateState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for UpdateState

impl PartialEq for UpdateState

fn eq(&self, other: &UpdateState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for UpdateState

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
