Crate random_branch[−][src]
Provides a macro to select a random branch.
This crate provides the branch
and
branch_using
macro, which will
execute randomly one of the given expressions.
It is maybe best visualized by the following example:
branch!( println!("First line."), println!("Second line?"), println!("Third line!"), );
This will be turned into something similar to this:
match rand::thread_rng().gen_range(0..3) { 0 => println!("First line."), 1 => println!("Second line?"), 2 => println!("Third line!"), _ => unreachable!(), }
For more details see branch
and
branch_using
. The basic difference between them is,
that branch
uses rand::thread_rng()
whereas
branch_using
uses the the given rand::Rng
.
