Struct Ready

pub struct Ready { /* private fields */ }

A synchronization primitive that can be used to block a thread until a value is ready. The procedure is as follows:

1. The Caller calls step(NOT_READY) to indicate that it is about to start the initialization process.
2. The Caller initializes the value.
3. The Caller calls step(IN_TRANSIT) to indicate that the value is ready. If step 1 fails, the value is already being initialized and the Caller must wait until is() returns true.

Implementations

impl Ready

pub const fn new() -> Self

Initializes a new Ready.

pub fn step(&self, from: u8) -> bool

Move the Ready to the next state, if it is in state from.

pub fn is(&self) -> bool
