我的程序在我的本地机器上按预期工作。它以 Emacs “Spook” 游戏 (Mx spook) 的方式从文本文件中打印随机行。文本文件位于src/spook.lines
.
C:\Users\datan>spooks
domestic Eiffel Tower Euzkadi Ta Askatasuna Euzkadi Ta Askatasuna minefield
C:\Users\datan>spooks
Uzi White House secret Sivi Vukovi divers
C:\Users\datan>spooks
Hizb-i-Islami smallpox US Airways SWAT plague
C:\Users\datan>
但是如果我将它作为 crate 发布并安装它,则找不到文本文件(因为src/spook.lines
如果程序是从 crates.io 安装的,则它不在其中):
C:\Users\datan>docker run -it rust bash

(no output because src/spook.lines is not there)
我包含文件的方式是:
let file = File::open("src/spook.lines")?;
为什么我不能只告诉货物/板条箱包装包含文本文件?首选方式是什么?我的意思是即使我将文件包含在某个目录中,它也不会在PATH
执行中,因为程序可能从任何地方运行。
