Struct RelationCatalogOids 

pub struct RelationCatalogOids {
    pub relation: u32,
    pub row_type: Option<u32>,
    pub array_type: Option<u32>,
    pub rule: Option<u32>,
}

Relation OIDs as the database’s counter allocated them, in PostgreSQL’s order: the relation, the array type, the row type and then a view’s rule. Relations created before OIDs were recorded derive them from their identity instead, and never change them.

Fields

relation: u32

row_type: Option<u32>

array_type: Option<u32>

rule: Option<u32>

Implementations

impl RelationCatalogOids

pub fn legacy(kind: RelationOidKind, object_id: &[u8; 16]) -> Self

The OIDs a relation created before OIDs were recorded derives from its identity. Such relations have no recorded array type.

pub fn reltype(&self) -> u32

The row type OID pg_class.reltype reports: zero for relations without one.

pub fn claimed(&self) -> impl Iterator<Item = u32>

Every OID the relation claims, for occupancy checks.

pub fn is_valid_for(&self, kind: RelationOidKind) -> bool

Whether the OIDs are well formed for the kind: every recorded OID is a user OID, and exactly the companions the kind has are present.
