How to find
format!
topic in the Rust documentation ? I had seen it once.
by Steve Klabnik and Carol Nichols, with contributions from the Rust Community
I need to print
12345678 as 12 345 678
12345678.9 as 12 345 678.90
The full documentation is in the std library reference:
Unfortunately, it doesn't look like there's any support for thousands separators in there, so you'll need to either write that yourself or find a third-party crate. Maybe someone here can recommend one; I'm not familiar with any.
If you need a specific locale formatting you'll need to use a third party crate like num-format. The standard library won't be able to that. And internalization is probably better left out of a standard library.
To be clear. The specific format you're looking for is locale specific to a few regions.
Edit: correction the format you describe "1 000 000.00" doesn't exist anywhere, so you'll have to settle for an existing one or make a custom one.
https://docs.rs/format_num_pattern uses patterns similar to javas DecimalFormat, and has i18n support.
