q

为疲惫的Rust程序员提供的快速且简单的调试工具。

示例用法

examples/simple.rs

#[macro_use]
extern crate q_debug;

fn hello(name: &str) -> String {
    q!(name);
    format!("Hello, {}!", name)
}

fn main() {
    // No message
    q!();

    // Identifier
    let name = "SteadBytes";
    q!(name);

    // Returns expression values
    let greeting = q!(hello(name));
    q!(greeting);

    q!(Some(42));
}

使用以下命令运行上述代码：cargo run --example simple 将以下内容写入 $TMP_DIR/q (/tmp/q 在Linux上)

[19:13:49 ThreadId(1) examples/simple.rs simple::main:11]
>
> name = "SteadBytes"
[19:13:49 ThreadId(1) examples/simple.rs simple::hello:5]
> name = "SteadBytes"
[19:13:49 ThreadId(1) examples/simple.rs simple::main:18]
> hello(name) = "Hello, SteadBytes!"
> greeting = "Hello, SteadBytes!"
> Some(42) = Some(42)
