§The Code Struct.

§Example

use c_emit::Code;

let mut code = Code::new();

code.exit(1);

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

Implementations§

Source §

impl Code<'_>

Source

pub fn new() -> Self

§Create a new C Code object.

§Example

use c_emit::Code;

let code = Code::new();

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

Source

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

§Add the exit code to the main function.

§Example

use c_emit::Code;

let mut code = Code::new();

code.exit(1);

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

Source

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

§#include < any file into the C Code. >

§Example

use c_emit::Code;

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());

Source

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

§Call a function WITHOUT arguments.

§Example

use c_emit::Code;

let mut code = Code::new();

code.call_func("printf");

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

Source

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

§Call a function WITH arguments.

§Example

use c_emit::{Code, CArg};

let mut code = Code::new();

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

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

Source

pub fn new_var<S: AsRef<str>>(&mut self, name: S, value: VarInit<'_>)

§Make a new variable.

§Example

use c_emit::{Code, CArg, VarInit};

let mut code = Code::new();

code.new_var("a", VarInit::String("hello"));

assert_eq!(code.to_string(), r#"
int main() {
char a[]="hello";
return 0;
}
"#.trim_start().to_string());
