Enum RequiredField 

#[non_exhaustive]
pub enum RequiredField {
    TenantId,
    DocId,
    ReceivedAt,
    OriginalSource,
}

Metadata identifiers that can be enforced via MetadataPolicy.

This enum defines the metadata fields that can be marked as required. It is marked #[non_exhaustive] to allow future additions without breaking existing code.

Required Fields

• TenantId: Tenant identifier for multi-tenant isolation
• DocId: Document identifier (caller must provide, no derivation)
• ReceivedAt: Timestamp when content was received
• OriginalSource: Human-readable source reference

Examples

use ingest::{MetadataPolicy, RequiredField};

let policy = MetadataPolicy {
    required_fields: vec![
        RequiredField::TenantId,
        RequiredField::DocId,
    ],
    ..Default::default()
};

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

TenantId

Require the tenant_id field to be present in metadata.

When required, callers must explicitly provide a non-empty tenant ID. The default_tenant_id fallback is not used.

DocId

Require the doc_id field to be present in metadata.

When required, callers must explicitly provide a document ID. No UUIDv5 derivation is performed.

ReceivedAt

Require the received_at timestamp to be present in metadata.

When required, callers must provide a timestamp. The default (current time) is not applied.

OriginalSource

Require the original_source field to be present in metadata.

When required, callers must provide a source reference.

Trait Implementations

impl Clone for RequiredField

fn clone(&self) -> RequiredField

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RequiredField

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RequiredField

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RequiredField

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for RequiredField
