-/// Represents a constraint definition for a parameter selection.
-///
-/// This structure describes the constraints that a command-line parameter (Picker parameter item)
-/// should satisfy, including its full name list (with aliases), short name form, and whether it is
-/// positional.
-///
-/// # Field Descriptions
-///
-/// - `full`: Full name or alias list. For example, `["config", "cfg"]` means the parameter can be
-///   matched with either `--config` or `--cfg`. Must contain at least one non-empty string.
-///
-/// - `short`: Short name (single character). For example, `Some('c')` means it can be passed using
-///   the `-c` form. If set to `None`, the short name form is not supported.
-///
-/// - `positional`: Whether the parameter is positional (i.e., an argument without a flag).
-///   - `true`: The parameter is positional; it is matched by its position in the command line rather
-///     than by a `--name` or `-n` flag.
-///   - `false`: The parameter is a named (flag-based) parameter.
-///
-/// - `_type`: PhantomData to hold the type parameter.
