class Cucumber::Messages::StepMatchArgument

Represents the StepMatchArgument message in Cucumber’s message protocol.

*

Represents a single argument extracted from a step match and passed to a step definition.
This is used for the following purposes:
- Construct an argument to pass to a step definition (possibly through a parameter type transform)
- Highlight the matched parameter in rich formatters such as the HTML formatter

This message closely matches the `Argument` class in the `cucumber-expressions` library.
