so is there no other way of checking for nightly in your code other than via a "nightly" feature?
there is a discussion about it, but I don't think it concluded into anything concrete.
Has anyone used tiberius to connect to MSSQL Servers? I'm trying to connect with it to a fresh SQL Server 2017 for Linux inside a docker container but always get an invalid connection state. Connecting with mssql-tools works though.
What's the right way to call a command? Use case: Calling a user input string as shell script (e.g. "cat myfile"), I don't care about the output, I actually would ideally want my program to call that command and immediately exit (with the user input command taking over stdout as if they'd entered it in a normal shell). Is that possible?
so basically you want to replace your program with a "called" one, right?
if yes, then consider using the
exec method: https://doc.rust-lang.org/std/os/unix/process/trait.CommandExt.html#tymethod.exec
You could also try this if I didn't mis-interprete your question:
use std::process::Command;
fn main() {
let file_name = format!("myfile");
let output = Command::new("cat")
.args(&[&file_name[..]]) // you can also pass in more arguments, by filling it in the outer array
.output();
match output {
Ok(_) => {/* do some actions */ },
Err(_err) => { /* do some action */ }
}
}
Anyone got clue why that doesn't work?
That's because only
one mutable ref to an value can exist per time
and since you are creating the mutable borrow
ref mut _a, you are not allowed to create the next mutable borrow ref mut _b
Hmm, I think that box is the problem (not sure why exactly -
*r?), because https://play.rust-lang.org/?gist=aa24246218bf0d7d46a873a6315911cc works fine
does anybody know how to edit firefox to show my self signed ssl as EV
@smarlewy looks like you cannot, because every CA has it's own field for marking certificate as EV https://en.wikipedia.org/wiki/Extended_Validation_Certificate#Extended_Validation_certificate_identification and browsers know them
so.. maybe i can edit the source code
to add mine too
or contact firefox?
when i build a project from scratch, I end up creating a lot of data in my deps directories. My final executable that pulls in a lot of libraries is 17M but the deps dir is 1.3G. This appears to be largely due to DWARF data but a lot of this is repeated between files.
for f in $(find . -type d -name DWARF) ; do nm $f/* | awk '{print $3}'; done | sort | uniq -c | sort -n | less
$ dust
1.2G .
1.2G └─┬ target
1.2G └─┬ debug
1.1G ├─┬ deps
then map this across all projects I have checked out (... im a drive-by patch gremlin), i kinda feel it's a problem. Is there any rfc i can track regarding an equiv of a .m2 directory that could collect all the versions to reduce the proliferaiton?
