Comparing Vectors in Move with Mappings in Solidity

Question

I’m trying to understand the differences between vectors in Move and mappings in Solidity. I’ve heard that they differ in terms of key types and iteration capabilities, but I’m not clear on the specifics. Can someone break down the main differences?

mssoni · Answer

A Move Table is quite similar to a Solidity mapping rather than a vector. Here are some key differences: vectors in Move are keyed strictly by integers, while Tables can use any type as a key. vectors come with a size limit, whereas Tables can store an unlimited number of elements. Iterating over vectors is straightforward; however, Tables do not support direct iteration similar to mappings, although you can use LinkedTable for iteration purposes.
