cbsk_base is a locked version cargo crates
you can use cbsk_base lock commonly used cargo crates versions
cbsk_base also supports some custom trait, like ToJson,FromJson and some macro

now locked version

serde example

use serde_derive_json,
the struct impl Serialize, will auto impl ToJson
the struct impl Deserialize, will auto impl FromJson

Cargo.toml file :

cbsk_base = { version = "2.1.2", features = ["serde_derive_json"] }

main.rs file :

use cbsk_base::json::from_json::FromJson;
use cbsk_base::json::to_json::ToJson;
use cbsk_base::serde::{Deserialize, Serialize};

#[derive(Serialize, Deserialize, Default, Debug)]
#[serde(crate = "cbsk_base::serde")]
struct A {
    data: String,
}

fn main() {
    let a = A::default();
    let json = a.to_json();
    println!("a is {json:?}"); // a is Ok(Object {"data": String("")})

    let a = A::from_json(json.unwrap());
    println!("a is {a:?}"); // a is Ok(A { data: "" })
}

option macro example

Cargo.toml file :

cbsk_base = { version = "2.1.2", features = ["macro", "anyhow"] }

main.rs file :

use cbsk_base::anyhow;

fn main() {
    let a = try_get_option();
    println!("a is {a:?}"); // a is Ok("hello world")
    exec_option();
}

fn try_get_option() -> anyhow::Result<String> {
    let a = Some("hello world".to_string());
    // match Option if is Some,
    // will be return value if is Nome,
    // will be return custom value and exit method
    Ok(cbsk_base::match_some_return!(a,Err(anyhow::anyhow!("a is none"))))
}

fn exec_option() {
    let a = Some("hello world".to_string());
    // match Option if is Some,
    // will be return value if is Nome,
    // will be return custom value
    let a = cbsk_base::match_some_exec!(a,{
        // do something, you can exit method, or break String
        println!("a is None");// will not output, because a not None
        return;
    });
    println!("a is {a}"); // a is hello world
}

root_path example

Cargo.toml file:

cbsk_base = { version = "2.1.2", features = ["root_path"] }

main.rs file:

fn main() {
    // print the path where the program is located
    let root_path = cbsk_base::root_path();
    println!("root path is {root_path}");
}
