Struct ValueMeta 

pub struct ValueMeta {
    pub grade: ValueGrade,
    pub provenance: Vec<ProvenanceClass>,
    pub sources: Vec<String>,
    pub as_of_ms: AsOf,
    pub basis: Basis,
    pub fields: Option<BTreeMap<String, ValueMeta>>,
    pub items: Option<Vec<ValueMeta>>,
    pub entries: Option<BTreeMap<String, ValueMeta>>,
}

Value metadata (spec 032, 3.2.2): carried by every input and step value of a plan 3 evaluation. A record carries one per field, a list one per item and a map one per entry, in the optional members.

Fields

grade: ValueGrade

provenance: Vec<ProvenanceClass>

Sorted, duplicate-free.

sources: Vec<String>

Sorted, duplicate-free source names.

as_of_ms: AsOf

basis: Basis

fields: Option<BTreeMap<String, ValueMeta>>

items: Option<Vec<ValueMeta>>

entries: Option<BTreeMap<String, ValueMeta>>

Implementations

impl ValueMeta

pub fn ungraded(basis: Basis) -> Self

Metadata to which nothing graded contributed.

pub fn combination<'a>( parts: impl IntoIterator<Item = &'a ValueMeta>, basis: Basis, ) -> Self

The combination of spec 032, 3.2.2 (minimum graded grade, union of provenance and sources, oldest as-of) under basis, without parts.

Trait Implementations

impl Clone for ValueMeta

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValueMeta

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ValueMeta

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ValueMeta

impl JsonSchema for ValueMeta

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 ValueMeta

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for ValueMeta

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
