# singleValueContainer()

Returns an encoding container appropriate for holding a single primitive
value.

```
func singleValueContainer() -> any SingleValueEncodingContainer
```

## Return Value

A new empty single value container.

## Discussion

You must use only one kind of top-level encoding container. This method
must not be called after a call to `unkeyedContainer()` or
`container(keyedBy:)`, or after encoding a value through a call to
`singleValueContainer()`
