什么是自由变量? 其实你在上一节的末尾已经见识过了, 让我们再把那部分的代码贴出来: fnmain(){leta=1;fnprint_a(){println!("{}",a);}} 让我们忽略先前的编译错误, 并且假设这部分代码能成功编译: 在外层函数main 中, 我们定义了a, 它是在 main 函数中产生的, 它的一切都被 main 函数所知晓, 所...

With this capability, -Csplit-debuginfo=unpacked will split debuginfo into multiple .dwo DWARF object files, while -Csplit-debuginfo=packed will produce a single .dwp DWARF package along with an output binary with all debuginfo packaged together. APIs have been stabilized such as std::backtrace::...
I've written 3 tutorials to show you how to create a service enabled Android application that performs all of it's network I/O in a background thread (not the UI thread). These tutorials are split into three parts. This tutorial shows you how to use background threads to perform long ...
This option controls whether debug information is split across multiple files or packed into a single file. Note This option is unstable on other platforms. Added tier 3* support for aarch64_be-unknown-linux-gnu, aarch64-unknown-linux-gnu_ilp32, and aarch64_be-unknown-linux-gnu_ilp32 tar...
