Struct AttestedList 

pub struct AttestedList {
    pub values: Vec<String>,
    pub provenance: FieldProvenance,
    pub source: String,
    pub reason: Option<String>,
}

A list with its provenance. The distinction a bare Vec cannot make is the one that matters here: depends_on: [] in the record is an authored empty list, and a record with no depends_on key is unknown. Both are empty; only one is a statement.

Fields

values: Vec<String>

The items, in the order the record or the derivation produced them. Empty for an authored empty list and for an unknown field alike; provenance tells them apart.

provenance: FieldProvenance

Where they came from.

source: String

The one place a reader goes to check them.

reason: Option<String>

Why the provenance is what it is, when that is worth a sentence.

Implementations

impl AttestedList

pub fn explicit(values: Vec<String>, source: impl Into<String>) -> Self

A list the canonical record carried under this key, including an empty one.

pub fn derived(values: Vec<String>, source: impl Into<String>) -> Self

A list worked out by a rule that cannot be wrong about a readable repository.

pub fn inferred( values: Vec<String>, source: impl Into<String>, reason: impl Into<String>, ) -> Self

A list worked out by a rule that can be wrong, with the rule stated.

pub fn unknown(source: impl Into<String>, reason: impl Into<String>) -> Self

No list at all, and why there is none.

pub fn len(&self) -> usize

How many items, which is zero for an unknown list too.

pub fn is_empty(&self) -> bool

No items — for an authored empty list as well as for an unknown one.

Trait Implementations

impl Clone for AttestedList

fn clone(&self) -> AttestedList

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AttestedList

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AttestedList

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for AttestedList

impl JsonSchema for AttestedList

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 AttestedList

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
