Struct PhysicalSchema 

pub struct PhysicalSchema { /* private fields */ }

Immutable normalized evidence observed from a live provider catalog.

Implementations

impl PhysicalSchema

pub fn normalize( provider: ProviderName, schema: SchemaName, revision: RevisionName, tables: Vec<PhysicalTable>, ) -> Result<Self, &'static str>

Normalizes an observed catalog. Tables/indexes are unordered; columns are sorted by provider ordinal.

pub fn tables(&self) -> &[PhysicalTable]

Returns normalized tables.

pub fn id(&self) -> Result<RelationId, Error>

Returns the distinct physical identity.
