You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: list.rs
    path of file: ./repos/phaser/phaser/vendor/tokio/src/sync/mpsc
    
    the code of the file until where you have to start completion: //! A concurrent, lock-free, FIFO list.

use crate::loom::sync::atomic::{AtomicPtr, AtomicUsize};
use crate::loom:
    
    pub(crate) fn push(&self, value: T) {
        // First, claim a slot for the value. `Acquire` is used here to
        // synchronize with the `fetch_add` in `reclaim_blocks`.
        let slot_index = self.tail_position.fetch_add(1, Acquire);

        // Load the current block and write the value
        let block = self.find_block(slot_index);

        unsafe {
            // Write the value to the block
            block.as_ref().write(slot_index, value);
        }
    }
