| # Using a Library |
| |
| To link a crate to this new library you may use `rustc`'s `--extern` flag. All |
| of its items will then be imported under a module named the same as the library. |
| This module generally behaves the same way as any other module. |
| |
| ```rust,ignore |
| // extern crate rary; // May be required for Rust 2015 edition or earlier |
| |
| fn main() { |
| rary::public_function(); |
| |
| // Error! `private_function` is private |
| //rary::private_function(); |
| |
| rary::indirect_access(); |
| } |
| ``` |
| |
| ```txt |
| # Where library.rlib is the path to the compiled library, assumed that it's |
| # in the same directory here: |
| $ rustc executable.rs --extern rary=library.rlib && ./executable |
| called rary's `public_function()` |
| called rary's `indirect_access()`, that |
| > called rary's `private_function()` |
| ``` |
