Crate nsrb 

Nifty Simple Ring Buffer (aka circular buffer) is a no_std crate that provides the ring! and manx! macros to easily create circular buffer data structure on the stack.

Example

// Import crate with #[macro_use] 
#[macro_use] extern crate nsrb;
 
// Use ring! macro to create circular buffer structure.
nsrb::ring!(pub(crate) ExampleRB[usize; 10]); 
 
// You can implement and access buffer inner variables if needed.
impl ExampleRB {
    pub fn head(&self) -> usize {
        self.head
    }
}
 
fn main() {
    // Use struct in code.
    let mut rb = ExampleRB::new();
    rb.push(5);
    assert_eq!(*rb.pop().unwrap(), 5);
    assert_eq!(rb.head(), 1);   // Using newly implemented method.
}

Macros

manx

Create a no tail Manx buffer data structure.

ring

Constants
