function: 一个Option<&'a str>类型的字段,表示函数名。如果不可用,则为None。 这个结构体的一个主要作用是提供给panic宏的panic!(...)宏在出现panic时输出更加详细的错误信息,包括panic的文件名、行号、列号和函数名等等。 此外,Location<'a>结构体还定义了一些辅助方法来获取和打印位置信息,包括: fn file(...
# 示例 \``` let output = another_function(10); println!("输出值: {}", output); \``` */ fn another_function(param: i32) -> i32 { param * 2 } 模块注释 在模块或文件级别,可以使用 //! 来为整个模块或文件添加文档注释: //! math crate //! //! `math` 是一个演示如何使用文件...
通过blocklist_function() 阻止一些函数的绑定; 通过opaque_type("__mingw_ldbl_type_t") 让该类型opaque,因为bindgen无法对其正确处理; 通过rustified_enum("*") 让任意enum成为Rust enum; 通过prepend_enum_name(false) 不预置enum name到常量或者新类型变量上; 通过derive_eq(true) 让Eq trait默认获得; 通...

egui uses a singleRwLockfor short-time locks on each access ofContextdata. This is to leave implementation simple and transactional and allow users to run their UI logic in parallel. Instead of creating mutex guards, egui uses closures passed to a wrapping function, e.g.ctx.input(|i| i.ke...

Your GUI code can easily live in a simple function (no need for an object just for the UI). You don't have to worry about app state and GUI state being out-of-sync (i.e. the GUI showing something outdated), because the GUI isn't storing any state - it is showing the latest st...
