Struct PrimaryKeyModel 

pub struct PrimaryKeyModel { /* private fields */ }

PrimaryKeyModel

Ordered primary-key field metadata for one entity. The current execution engine consumes scalar projections, while this model carries the ordered field-list shape needed for composite primary keys.

Implementations

impl PrimaryKeyModel

pub const fn scalar(field: &'static FieldModel) -> Self

Build scalar primary-key metadata for existing generated/test models.

pub const fn ordered(fields: &'static [&'static FieldModel]) -> Self

Build ordered primary-key metadata from generated field references.

pub const fn len(&self) -> usize

Return the number of fields in this primary key.

pub const fn is_empty(&self) -> bool

Return whether this primary key has no fields.

pub const fn is_scalar(&self) -> bool

Return whether this primary key is the scalar one-field case.

pub const fn first_field(&self) -> &'static FieldModel

Return the first primary-key field.

Composite-aware code should consume fields() when it needs full row identity. This helper exists only for metadata surfaces that still carry one primary-key field pointer alongside ordered primary-key metadata.

pub const fn fields(&self) -> PrimaryKeyModelFields

Iterate over ordered primary-key fields.

Trait Implementations

impl Debug for PrimaryKeyModel

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

Formats the value using the given formatter.
