本文简要介绍rust语言中 Function std::env::set_current_dir 的用法。用法pub fn set_current_dir<P: AsRef<Path>>(path: P) -> Result<()> 将当前工作目录更改为指定路径。 如果操作失败,则返回 Err 。 例子 use std::env; use std::path::Path; let
executable: Option<String>, args: Option<Vec<String>, current_dir: Option<String>, 只需要将上述生成的字段嵌入CommandBuilder结构体中,一个带字段的CommandBuilder 结构体便生成好了: quote! { pub struct CommandBuilder { #builder_fields } } 在为CommandBuilder类添加字段后,Command::builder函数中生成...
简单起见,我们先假定Command结构体中只有必填单选项,无选填或多选项,简化后的Command类如下: #[derive(Builder)]pubstructCommand{executable:String,args:Vec<String>,current_dir:String,} 首先实现Command类中的builder函数: implCommand{pubfnbuilder()->CommandBuilder{CommandBuilder}}pubstructCommandBuilder; 为此派...
开发过程宏时经常需要处理结构体或枚举体上的属性参数,如下 Command 结构体的args字段有属性each = "arg", 代码语言:rust AI代码解释 #[derive(Builder)]pubstructCommand{executable:String,#[builder(each ="arg")]args:Vec<String>,#[builder(each ="env")]env:Vec<String>,current_dir:Option<String>,} ...

--target-dir directory所有生成的工件和中间文件的目录。也可以用CARGO_TARGET_DIR环境变量或build.target-dir配置值https://doc.rust-lang.org/cargo/reference/config.html来指定。默认为工作空间根目录中的target。 --out-dir directory将最终工件复制到此目录。此选项不稳定,仅在nightly channel上可用,并且需要-...
