Struct CompleteReadProjection 

pub struct CompleteReadProjection { /* private fields */ }

The complete materialized read facet.

Implementations

impl CompleteReadProjection

pub fn new( fields: Vec<ReadFieldProjection>, roles: BTreeMap<RoleId, ReadRoleProjection>, nominal_upcasts: Vec<TypeId>, ) -> Result<Self, Diagnostic>

Construct one complete-read shape.

pub fn with_role_upcasts( self, role_upcasts: BTreeMap<RoleId, Vec<RoleId>>, ) -> Result<Self, Diagnostic>

Attach active-child-role to ordered ancestor-role read mappings.

pub fn fields(&self) -> &[ReadFieldProjection]

Return owned-attribute fields in semantic order.

pub const fn roles(&self) -> &BTreeMap<RoleId, ReadRoleProjection>

Return active role fields.

pub fn nominal_upcasts(&self) -> &[TypeId]

Return legal nominal upcast model identities, nearest first.

pub const fn role_upcasts(&self) -> &BTreeMap<RoleId, Vec<RoleId>>

Return specialized child-role to nearest-first ancestor-role mappings.
