Enum CatalogWritePolicy 

pub enum CatalogWritePolicy {
    Mutable,
    Sealed,
    AppendOnly,
    Derived,
}

Write policy governing how rows of a catalog table may change.

See the README section “Contract: registry catalog substrate” for how the registry’s tables map onto these policies.

Variants

Mutable

Insert, replace, and delete are all permitted.

Sealed

A key may be inserted once and then never changed or deleted.

AppendOnly

Keys may be inserted but never changed or deleted.

Derived

Direct writes fail; rows are derived from other tables.

impl Eq for CatalogWritePolicy

impl PartialEq for CatalogWritePolicy

fn eq(&self, other: &CatalogWritePolicy) -> 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.
