Struct TemplateProvenance 

pub struct TemplateProvenance {
    pub template: String,
    pub digest: Sha256Digest,
    pub body_digest: Sha256Digest,
    pub answers_digest: Sha256Digest,
}

What a task or a document created or regenerated from a template records under TemplateProvenance::KEY.

An item created from a plain body records none.

Fields

template: String

The template it was rendered from: the absolute path of a template file, or a loader document’s reference verbatim. Recorded whole, whatever its length.

digest: Sha256Digest

The chain digest the content was rendered with.

body_digest: Sha256Digest

The SHA-256 of the item’s content exactly as written.

answers_digest: Sha256Digest

The SHA-256 of the resolved answers — defaults applied — as canonical JSON: keys sorted, no insignificant whitespace, UTF-8.

Implementations

impl TemplateProvenance

pub const KEY: &'static str = MetadataKey::TEMPLATE_KEY

The reserved metadata key this entry lives under: onetaskgraph.template.

pub fn of( template: impl Into<String>, rendered: &RenderedTemplate, ) -> Result<Self, TemplateError>

The provenance of rendered, rendered from the template template names.

Errors

TemplateError::Malformed when the rendering’s digest is not one — a RenderedTemplate a caller assembled by hand rather than a render answered.

pub fn read(metadata: &BTreeMap<String, Value>) -> Result<Option<Self>, String>

The provenance metadata records, None when it records none.

Errors

Why the entry under Self::KEY is not one this product writes, when it is there and is not: not the four strings, or a digest that is not sha256: and 64 lowercase hex digits.

pub fn to_value(&self) -> Value

The entry as the JSON value a metadata map holds.

Trait Implementations

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
