Struct Liveness 

pub struct Liveness {
    pub alive: bool,
    pub version: String,
    pub commit: String,
    pub dirty: Option<bool>,
}

The answer to “is this process alive”: the cheapest true thing this executable can say about itself. Deliberately not a summary of anything — a probe that grew an opinion would stop reporting the one fact the platform polls it for.

Fields

alive: bool

Always true. A process that could not answer would not answer at all, which is the signal.

version: String

This executable’s version, so a rolling deployment can tell which build answered.

commit: String

The commit this executable was built from, in full, or unknown when the build could not name one. A version is what a build calls itself and two revisions share it; this is what a deployment is checked against. Never omitted: an absent field would read as a server too old to say, and unknown is a different, truthful answer.

dirty: Option<bool>

Whether that commit’s tree carried uncommitted changes when this executable was built; null when the build did not know.

Trait Implementations

impl Clone for Liveness

fn clone(&self) -> Liveness

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Liveness

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Liveness

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Liveness

impl JsonSchema for Liveness

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for Liveness

fn eq(&self, other: &Liveness) -> 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 Liveness

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
