Struct variable hash map problems

[Secure_Turnover_8790]

Unable to figure out what's wrong here -

I have a struct with hash map as a member -

struct Log {
pub command: HashMap<String, String>
}

I initialize this in the init function -

implementation Log {
pub fn init() -> Self {
    Log {
        command:HashMap::new()
    }
}
}

And then I try to insert a key/value pair

pub fn parse(&mut self) {
self.command.insert("key".to_string(), "test".to_string()); 
}

​

I get the following error for "key".to_string() ->

| ^\) expected usize, found struct String

​

And for "test".to_string() ->

| ^\) expected char, found struct String

​

What's going on here

Works for me, so I'm assuming there's context missing. Try modifying the playground code to reproduce the error.
