  It looks like you are trying to parse a module, but the module name is not in the correct format.

In Rust, a module is a collection of related functions and variables that are defined together. The name of a module is typically a capitalized identifier, and it should be followed by a colon and the module body.

Here is an example of a valid module:
```
mod MyModule {
    // module body
}
```
In this example, the module name is `MyModule`, and the module body is the code that is defined inside the curly braces.

To fix the error, you can try adding a colon after the module name, like this:
```
mod MyModule: {
    // module body
}
```
This will define a module named `MyModule` with the specified module body.
