如何在 Rust 中std::ffi::CString从 a创建 aString? 假设String已经存储在一个可以在必要时移动的变量中,而不是像许多构造CString. 我研究了两者的文档CString:https ://doc.rust-lang.org/std/ffi/struct.CString.html 和String: https://doc.rust-lang.org/std/string/struct.String.html 我仍然没有看到路。

摘要:Rust 得以在编程语言中火速崛起的原因之一,就是它能够与 C 语言进行互操作。因此在本文中,作者介绍了在 Rust 与 C 之间传递字符串的七种方式,这些方法不仅可用于传递字符串,也可用于其他数据。 原文链接:https://dev.to/kgrech/7-ways-to-pass-a-string-between-rust-and-c-4ieb ...
本文简要介绍rust语言中 std::ffi::CString.into_bytes_with_nul 的用法。用法pub fn into_bytes_with_nul(self) -> Vec<u8> 等效于 CString::into_bytes() ,只是返回的向量包含尾随 nul 终止符。 例子 use std::ffi::CString; let c_string = CString::new("foo").expect("CString::new failed");...

I suggest merging that one first and rebasing this PR on top of it to see the pipeline succeed first. 👍 1 cmdline: make the init option a String instead of CString … 147bba5 hnez mentioned this pull request Jan 29, 2025 ci: add more checks and run against older rust versions...
