NoKey

Struct NoKey 

Source
pub struct NoKey(/* private fields */);
Expand description

Represents a path component without a key. This is useful when the container only ever holds a single key, which is the case for any 1-tuple struct.

For an example usage, see the implementation of Inner for Option.
