我试图证明 C 可以调用 Rust 库。它有效，但是当我监视程序的内存使用情况时，它不断变得越来越大。

货物.toml：

[lib]
name="test_ccallr"
crate-type=["cdylib"]
path = "src/lib.rs"

[dependencies]
libc = "0.2"

C代码：

[lib]
name="test_ccallr"
crate-type=["cdylib"]
path = "src/lib.rs"

[dependencies]
libc = "0.2"

我使用以下命令构建 C 代码：

#include <stdio.h>
#include <string.h>
#include <unistd.h>
#include <stdlib.h>

struct Payload_t{
    char* data;
    int len;
};

int show_str(char* raw, struct Payload_t *data);

int main()
{
    while(1){
        char * p_raw = "hlease print it !ello this is string from c, please print it !";
        char * p_raw_ = "hhello this is another …
