Struct Frontmatter 

pub struct Frontmatter {
    pub id: Option<String>,
    pub version: Option<String>,
    pub description: Option<String>,
    pub model: Option<ModelHints>,
    pub input: Option<InputSpec>,
    pub output: Option<OutputSpec>,
    pub evals: Option<Vec<Eval>>,
    pub intentry: Option<IntrEntryMeta>,
    pub extra: HashMap<String, Value>,
}

YAML frontmatter between --- fences.

Fields follow the Dotprompt spec + Intentry extensions under the intentry: key.

Fields

id: Option<String>

Stable kebab-case identifier, unique within a Space. Max 64 chars. Required for Tier 2+.

version: Option<String>

Semver version string (e.g. "1.2.0"). Required for Tier 2+.

description: Option<String>

One-line human description of what the prompt does.

model: Option<ModelHints>

Model preferences and generation parameters.

input: Option<InputSpec>

Input variable declarations.

output: Option<OutputSpec>

Output shape expectations (for evals and schema validation).

evals: Option<Vec<Eval>>

Eval cases. Presence of this field (non-empty) promotes to Tier 3.

intentry: Option<IntrEntryMeta>

Intentry-specific extensions (tags, license, parent fork info, etc.).

extra: HashMap<String, Value>

Any unknown fields are preserved as raw JSON for forward-compatibility.

Trait Implementations

impl Clone for Frontmatter

fn clone(&self) -> Frontmatter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Frontmatter

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Frontmatter

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Frontmatter

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
