Macro serde_json_lodash::to_safe_integer

macro_rules! to_safe_integer {
    () => { ... };
    ($a:expr $(,)*) => { ... };
    ($a:expr, $($rest:tt)*) => { ... };
}

Based on to_safe_integer()

Examples:

#[macro_use] extern crate serde_json_lodash;
use serde_json::json;
assert_eq!(
  to_safe_integer!(json!(3.2)),
  json!(3)
);
//assert_eq!(
//  to_safe_integer!(json!(isize::MIN)), // serde_json will convert this to Number(-9223372036854775808)
//  json!(0)
//);
//assert_eq!(
//  to_safe_integer!(json!(f64::INFINITY)), // serde_json will convert this to Value::Null
//  json!(9007199254740991) // serde_json will convert this to Number(-1)
//);
assert_eq!(
  to_safe_integer!(json!("3.2")),
  json!(3)
);
