Why I am not able to see the col_index label and value and c label and value in my output? Please help!
row.chars()
.enumerate()
.map(|(col, c)| match c {
CRCT => CRCT,
_ => count_char(col_index, row_index, charfield),
})
.inspect(|col_index| println!("col_index {}", &col_index))
.inspect(|c| println!("c {}", &c))
.collect::<String>()
})
.collect()
//and so on
What error are you getting?
Also, could you update the code to match the formatting guidelines?
No compile error or warning. Just no output.
Sorry about formatting. I will correct it tomorrow.

Why I am not able to see the col_index label and value and c label and value in my output? Please help!
Attempted format correction on Android Phone:
row.chars()
.enumerate()
.map(|(col, c)| match c {
CRCT => CRCT,
_=> count_char(col_index, row_index, charfield),
})
.inspect(|col_index| println!("col_index {}", &col_index))
.inspect(|c| println!("c {}", &c))
.collect::()
})
.collect()
//and so
Could you provide a complete example please?
I tried copying your code snippet into the playground but it fails to compile due to a bunch of missing variables and functions. There was also a syntax error because you've got a trailing }).collect(), but I'm guessing that was an accident from when you copy/pasted the code into your post.
fn main() {
let row = "this is a string";
row.chars()
.enumerate()
.map(|(col, c)| match c {
CRCT => CRCT,
_ => count_char(col_index, row_index, charfield),
})
.inspect(|col_index| println!("col_index {}", &col_index))
.inspect(|c| println!("c {}", &c))
.collect::<String>();
}

error: could not compile `playground` due to 4 previous errors
Something that often helps people with reproducing your issue is if you can write up a minimal example on the playground. That way we have all the code and can hit the "build" button to see any compile errors you are having.
Thank you. I will work on runnable code on Playground.
