Struct RelationIdentity 

pub struct RelationIdentity {
    pub schema: String,
    pub name: String,
}

Durable identity of a SQL relation.

The schema and local name are stored separately so foo and public.foo can never become two physical catalog identities for the same SQL object.

Fields

schema: String

name: String

Implementations

impl RelationIdentity

pub fn new(schema: impl Into<String>, name: impl Into<String>) -> Self

pub fn qualified_name(&self) -> String

pub fn canonical_and_legacy_public_names(&self) -> Vec<String>

Physical owner keys that can refer to this relation. New writes use only the canonical qualified name. Catalog cleanup also accepts the former unqualified key for public relations so data written before relation identities became schema-aware cannot survive its owner.

pub fn from_legacy_name(value: &str) -> Result<Self, String>

Decode a SQL relation reference or a former flat catalog key. Unqualified objects belong to public. Quoted components preserve embedded dots and escaped quotes, so public.\"a.b\" is distinct from \"public.a\".b all the way down to physical storage keys.

pub fn from_legacy_index_name(value: &str, table: &Self) -> Self

Recover an index identity from the former flat index catalog. The stored value is a decoded local identifier rather than a relation reference, so dots and quotes remain part of the local name and the owning table supplies the schema.

pub fn parse_reference(value: &str) -> Result<(Option<String>, String), String>

Parse a possibly-unqualified SQL relation reference without choosing a search-path schema. Components use PostgreSQL double-quote escaping.

Trait Implementations
