Struct AttestedCount 

pub struct AttestedCount {
    pub value: Option<u32>,
    pub provenance: FieldProvenance,
    pub source: String,
    pub reason: Option<String>,
}

A count with its provenance. Separate from AttestedText because a wave, a commit tally and an evidence count are numbers a caller does arithmetic on, and a number rendered as a string is a number every client has to parse back.

Fields

value: Option<u32>

The number, absent exactly when the provenance is unknown.

provenance: FieldProvenance

Where it came from.

source: String

The one place a reader goes to check it.

reason: Option<String>

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

Implementations

impl AttestedCount

pub fn explicit(value: u32, source: impl Into<String>) -> Self

A number the canonical record carried under this key.

pub fn derived(value: u32, source: impl Into<String>) -> Self

A number worked out from records or from git.

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

No number, and why there is none.

Trait Implementations

impl Clone for AttestedCount

fn clone(&self) -> AttestedCount

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AttestedCount

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AttestedCount

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for AttestedCount

impl JsonSchema for AttestedCount

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 AttestedCount

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
