Arguments

• key: [b256] - The storage slot to load the value from.

Returns

• [Option<raw_slice>] - If no value was previously stored at key, None is returned. Otherwise,
  Some(value) is returned, where value is the value stored at key.

Number of Storage Accesses

• Reads: 2

Examples

use std::{alloc::alloc_bytes, storage::{write_slice, read_slice}};

fn foo {
    let slice = asm(ptr: (alloc_bytes(1), 1)) { ptr: raw_slice };
    assert(read_slice(b256::zero()).is_none());
    write_slice(b256::zero(), slice);
    let stored_slice = read_slice(b256::zero()).unwrap();
    assert(slice == stored_slice);
