Struct FrontMatter 

pub struct FrontMatter {
    pub schema_version: Option<String>,
    pub created_at: Option<String>,
    pub updated_at: Option<String>,
    pub created_by: Option<String>,
    pub updated_by: Option<String>,
    pub change_id: Option<String>,
    pub module_id: Option<String>,
    pub integrity: Option<IntegrityMetadata>,
    pub extra: BTreeMap<String, Value>,
}

Parsed YAML front matter metadata for an Ito artifact.

Timestamps are stored as RFC 3339 strings to avoid requiring the serde feature on chrono. Use FrontMatter::created_at_dt and FrontMatter::updated_at_dt to parse them into DateTime<Utc>.

Fields

schema_version: Option<String>

Schema version for forward compatibility.

created_at: Option<String>

When the artifact was first created (RFC 3339 UTC string).

updated_at: Option<String>

When the artifact was last updated (RFC 3339 UTC string).

created_by: Option<String>

Identity of the creator (optional).

updated_by: Option<String>

Identity of the last updater (optional).

change_id: Option<String>

Change identifier for integrity validation.

module_id: Option<String>

Module identifier for integrity validation.

integrity: Option<IntegrityMetadata>

Integrity metadata for corruption detection.

extra: BTreeMap<String, Value>

Additional fields not captured by the typed struct.

Implementations

impl FrontMatter

pub fn created_at_dt(&self) -> Option<DateTime<Utc>>

Parse created_at into a DateTime<Utc>, if present and valid.

pub fn updated_at_dt(&self) -> Option<DateTime<Utc>>

Parse updated_at into a DateTime<Utc>, if present and valid.

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.
