Struct CatalogTableSpec 

pub struct CatalogTableSpec {
    pub name: Symbol,
    pub policy: CatalogWritePolicy,
    pub owner: Option<Symbol>,
    pub required_fields: Vec<Symbol>,
    pub unique_fields: Vec<Vec<Symbol>>,
}

Specification of one catalog table: its name, write policy, owner, and field constraints.

Examples

let spec = CatalogTableSpec::new(Symbol::new("registry/libs"), CatalogWritePolicy::Mutable)
    .with_required_fields(vec![Symbol::new("manifest")]);
assert_eq!(spec.policy, CatalogWritePolicy::Mutable);
assert_eq!(spec.required_fields, vec![Symbol::new("manifest")]);

Fields

name: Symbol

Open symbol naming the table.

policy: CatalogWritePolicy

Write policy enforced on the table’s rows.

owner: Option<Symbol>

Optional owning library symbol.

required_fields: Vec<Symbol>

Fields every row of the table must carry.

unique_fields: Vec<Vec<Symbol>>

Field tuples that must be unique across the table’s rows.

Implementations

impl CatalogTableSpec

pub fn new(name: Symbol, policy: CatalogWritePolicy) -> Self

Creates a spec with the given name and policy and no further constraints.

pub fn with_required_fields(self, fields: Vec<Symbol>) -> Self

Returns the spec with its required fields replaced.

Trait Implementations

impl Clone for CatalogTableSpec

fn clone(&self) -> CatalogTableSpec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CatalogTableSpec

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

Formats the value using the given formatter.

impl Eq for CatalogTableSpec

impl PartialEq for CatalogTableSpec

fn eq(&self, other: &CatalogTableSpec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
