In the ebook "The rust programming language" chapter 12.3 "Refactoring to Improve Modularity and Error Handling" section "Splitting Code into a Library Crate" it said split the main.rs file and put some code into src/lib.rs file then move the /src/lib.rs into the scope of the binary crate by adding "use minigrep::Config;"
I m confusing here: it should use the same crate named minigrep, but how could I make it? I tried many ways but cannot make the result as tutorial. how to make a crate both binary and library?
main.rs will be the root of two entirely independent crate. The
main.rs crate will have a dependency on the
lib.rs crate, but not the other way around. So:
- When accessing something in the library crate from the library crate, you import with
- When accessing something in the binary crate from the binary crate, you import with
- When accessing something in the libary crate from the binary crate, you import with
your_crate_name will be whatever name you used in your
Thank you for detail reply, I fixed it!
