如何在 Rust 中打印 1 dec 和固定宽度的 F32

Question

Trying to replicate the following C printf invocation尝试复制以下 C printf 调用

printf("%6.1f %6.1f %6.1f\n", x, y, z);

in rust and I can't find it in the docs.在 rust 中，我在文档中找不到它。 I need 6 positions wide with 1 decimal place.我需要 6 个位置宽 1 个小数位。

First time I've been stumped finding what I need there.我第一次在那里很难找到我需要的东西。

Formatting strings are documented in the documentation for std::fmt .格式化字符串记录在std::fmt的文档中。

The equivalent of %6.1f would be {:6.1} : %6.1f的等价物是{:6.1} ：

println!("{:6.1} {:6.1} {:6.1}", x, y, z);
