I want to convert string to integer (i32) and if error I want it to return 0 using function bellow:
fn convertToInteger(a: []const u8) i32 {
return std.fmt.parseInt(i32, a, 10);
}
but it always gives this error:
error: expected type 'i32', found 'error{InvalidCharacter,Overflow}!i32'
return std.fmt.parseInt(i32, a, 10);
~~~~~~^

std.fmt.parseInt returns an error union (that's what the message is saying btw)
What you need to do is to catch this error and return 0 in that case
quaint parrot
how can I catch that error union?

Using the catch keyword 😁
You should probably take a look at the documentation about errors, it's pretty detailed and will give you a clearer picture: https://ziglang.org/documentation/0.10.1/#Errors
