Struct Codata 

Source 
pub struct Codata<F> { /* private fields */ }
Expand description

Codata<F> represents the greatest fixed point of the functor F.

Because Rust does not support infinite types directly, we model it as an explicit thunk: call unfold() to expose one layer of the codata on demand.

Implementations§

Source§

impl<F: 'static> Codata<F>

Source

pub fn new(unfold: impl Fn() -> F + 'static) -> Self

Construct a Codata from an unfolding thunk.

Source

pub fn unfold(&self) -> F
