Expand description
Enum for Join Restrictions policy.
Variants§
Unspecified = 0
A join is neither required nor restricted on any column. Default value.
JoinAny = 1
A join is required on at least one of the specified columns.
JoinAll = 2
A join is required on all specified columns.
JoinNotRequired = 3
A join is not required, but if present it is only permitted on ‘join_allowed_columns’
JoinBlocked = 4
Joins are blocked for all queries.

sourcepub fn as_str_name(&self) -> &'static str
pub fn as_str_name(&self) -> &'static str
String value of the enum field names used in the ProtoBuf definition.
The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.
sourcepub fn from_str_name(value: &str) -> Option<Self>
pub fn from_str_name(value: &str) -> Option<Self>
Creates an enum from field names used in the ProtoBuf definition.
