本文簡要介紹rust語言中 Function std::env::current_exe 的用法。用法pub fn current_exe() -> Result<PathBuf> 返回當前運行的可執行文件的完整文件係統路徑。 特定於平台的行為 如果可執行文件是通過符號鏈接調用的,則某些平台將返回符號鏈接的路徑,而其他平台將返回符號鏈接目標的路徑。 如果可執行文件在運行時...
std::env模块下有如下函数: args 返回命令行传递的参数 args_os 返回当前进程的参数 current_dir 返回当前的工作目录,该目录保存在PathBuf中 current_exe 返回当前可执行程序的全路径 home_dir 返回当前用户目录的路径 join_paths 添加一些环境变量到PATH这个变量中 remove_var 删除当前运行进程的环境变量(系统中的环...

事实上就是match Result的封装,当遇到Err(E)时会提早返回, ::std::convert::From::from(err)可以将不同的错误类型返回成最终需要的错误类型,因为所有的错误都能通过From转化成`Box<Error>`,所以下面的代码是正确的: use std::error::Error;use std::fs::File;use std::io::Read;use std::path::Path;...

std no longer prints backtraces on platforms where the running module must be loaded with env::current_exe, which can't be relied on. This release includes std binaries for the i586-unknown-linux-gnu, i686-unknown-linux-musl, and armv7-linux-androideabi targets. The i586 target is for old...
