        values: Vec<Value<String>>,
    },
}

AWS CloudFormation provides several built-in functions that help you manage your stacks. Use intrinsic functions in your templates to assign values to properties that are not available until runtime.

Variants

Join

Append a set of values into a single value, separated by the specified delimiter. If a delimiter is the empty string, the set of values are concatenated with no delimiter.

Fields

delimiter: String

The value you want to occur between fragments. The delimiter will occur between fragments only. It will not terminate the final value.

values: Vec<Value<String>>

The list of values you want combined.

Trait Implementations

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