Struct FlattenId 

pub struct FlattenId {
    pub separator: String,
}

Rewrite Value::Array record IDs to Text joined with Self::separator.

Scalar IDs are left unchanged. Relation edge IDs are also flattened when they are Arrays (endpoint Thing refs are flattened the same way so links stay consistent if a source emitted Array endpoint IDs).

Fields

separator: String

Joiner between composite key parts (default :).

Implementations

impl FlattenId

pub fn new(separator: impl Into<String>) -> Self

Create with an explicit separator.

Trait Implementations

impl Clone for FlattenId

fn clone(&self) -> FlattenId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FlattenId

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

Formats the value using the given formatter.

impl Default for FlattenId

fn default() -> Self

Returns the “default value” for a type.

impl InPlaceTransform for FlattenId
