Struct c_emit::Code

pub struct Code { /* private fields */ }

The Code Struct.

Example

use c_emit::Code;

fn main() {
    let mut code = Code::new();

    code.exit(1);

    assert_eq!(code.to_string(), r#"
int main() {
return 1;
}
"#.trim_start().to_string());
}

Implementations

impl Code

pub fn new() -> Self

Create a new C Code object.

Example

use c_emit::Code;

fn main() {
    let code = Code::new();

    assert_eq!(code.to_string(), r#"
int main() {
return 0;
}
"#.trim_start().to_string());
}

pub fn exit(&mut self, code: i32)

Add the exit code to the main function.

Example

use c_emit::Code;

fn main() {
    let mut code = Code::new();

    code.exit(1);

    assert_eq!(code.to_string(), r#"
int main() {
return 1;
}
"#.trim_start().to_string());
}

pub fn include(&mut self, file: &str)

#include < any file into the C Code. >

Example

use c_emit::Code;

fn main() {
    let mut code = Code::new();

    code.include("stdio.h");

    assert_eq!(code.to_string(), r#"
#include<stdio.h>
int main() {
return 0;
}
"#.trim_start().to_string());
}

pub fn call_func(&mut self, func: &str)

Call a function WITHOUT arguments.

Example

use c_emit::Code;

fn main() {
    let mut code = Code::new();

    code.call_func("printf");

    assert_eq!(code.to_string(), r#"
int main() {
printf();
return 0;
}
"#.trim_start().to_string());
}

pub fn call_func_with_args(&mut self, func: &str, args: Vec<CArg>)

Call a function WITH arguments.

Example

use c_emit::{Code, CArg};

fn main() {
    let mut code = Code::new();

    code.call_func_with_args("printf", vec![CArg::String("Hello, world!".to_string())]);

    assert_eq!(code.to_string(), r#"
int main() {
printf("Hello, world!",);
return 0;
}
"#.trim_start().to_string());
}
