Enum JoinCondition 

#[non_exhaustive]
pub enum JoinCondition {
    Unspecified,
    JoinAny,
    JoinAll,
    JoinNotRequired,
    JoinBlocked,
    UnknownValue(UnknownValue),
}

Enum for Join Restrictions policy.

Working with unknown values

This enum is defined as #[non_exhaustive] because Google Cloud may add additional enum variants at any time. Adding new variants is not considered a breaking change. Applications should write their code in anticipation of:

• New values appearing in future releases of the client library, and
• New values received dynamically, without application changes.

Please consult the Working with enums section in the user guide for some guidelines.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unspecified

A join is neither required nor restricted on any column. Default value.

JoinAny

A join is required on at least one of the specified columns.

JoinAll

A join is required on all specified columns.

JoinNotRequired

A join is not required, but if present it is only permitted on ‘join_allowed_columns’

JoinBlocked

Joins are blocked for all queries.

UnknownValue(UnknownValue)

If set, the enum was initialized with an unknown value.

Applications can examine the value using JoinCondition::value or JoinCondition::name.

Implementations

impl JoinCondition

pub fn value(&self) -> Option<i32>

Gets the enum value.

Returns None if the enum contains an unknown value deserialized from the string representation of enums.

pub fn name(&self) -> Option<&str>

Gets the enum value as a string.

Returns None if the enum contains an unknown value deserialized from the integer representation of enums.
