Enum DashboardMeasure 

pub enum DashboardMeasure {
    Exact,
    Count,
}

How a card’s value is read out of its source’s answer. Neither reading is arithmetic on the source’s behalf.

use majordomus_cli::capability::builtin::dashboard::DashboardMeasure;
use serde_json::json;

let answer = json!({ "status": "warn", "tallies": { "ok": 6 }, "overlaps": [1, 2] });
// exact: the value at the pointer, null when there is none
assert_eq!(DashboardMeasure::Exact.read(&answer, "/status"), json!("warn"));
assert_eq!(DashboardMeasure::Exact.read(&answer, "/tallies/fail"), json!(null));
// count: a number as it stands, a list or map by its length, and an omitted one is none
assert_eq!(DashboardMeasure::Count.read(&answer, "/tallies/ok"), json!(6));
assert_eq!(DashboardMeasure::Count.read(&answer, "/overlaps"), json!(2));
assert_eq!(DashboardMeasure::Count.read(&answer, "/tallies/fail"), json!(0));

Variants

Exact

The value at the pointer, exactly; null when the pointer resolves to nothing.

Count

The number at the pointer, or the length of the list or map there; 0 when the source left it out, which is how the sources say an empty list or a zero tally.

Implementations

impl DashboardMeasure

pub fn read(self, answer: &Value, pointer: &str) -> Value

Read the card’s value out of the source’s answer.

use majordomus_cli::capability::builtin::dashboard::DashboardMeasure;
use serde_json::json;
let answer = json!({ "issue": { "id": "I0001" } });
assert_eq!(DashboardMeasure::Exact.read(&answer, "/issue/id"), json!("I0001"));
assert_eq!(DashboardMeasure::Count.read(&answer, "/blockers"), json!(0));

Trait Implementations

impl Clone for DashboardMeasure

fn clone(&self) -> DashboardMeasure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DashboardMeasure

impl Debug for DashboardMeasure

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DashboardMeasure

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for DashboardMeasure

impl JsonSchema for DashboardMeasure

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 DashboardMeasure

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
