> A `pub` symbol is accessible outside the current crate; This is not universally true; it's more that pub makes it accessible to the enclosing scope. Wrapping in an extra "mod" so that this works in one file: mod foo { mod bar { pub fn baz() { } } pub fn foo() { bar::baz(); } } fn main() { // this is okay, because foo can call baz foo::foo(); // this is not okay, because bar is private, and so even though baz is marked pub, its parent module isn't foo::bar::baz(); }
