Struct ValueList 

pub struct ValueList<T>(/* private fields */);

Like Value, except it is used in place of lists of Values in templates.

For example, if you have a parameter called SubnetIds of type List<AWS::EC2::Subnet::Id> then, you can use ValueList::reference("SubnetIds") to reference it.

Implementations

impl<T> ValueList<T>

pub fn new<I>(values: I) -> ValueList<T>

where I: IntoIterator<Item = Value<T>>,

Create a new value list.

pub fn reference<S: Into<String>>(id: S) -> ValueList<T>

Create a new value list backed by a reference.

pub fn as_values(&self) -> Option<&[Value<T>]>

If the list contains values, return Some.

Return None otherwise.

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

If the list is a reference, return Some.

Return None otherwise.
