Automatically implement SpreadAllocate for ink! storage struct if all fields implement SpreadAllocate

3

Currently the ink! codegen does not implement `SpreadAllocate` for the `#[ink(storage)]` struct. This leads to us having to implement it manually in the adjusted ERC-20 example contract here: https://github.com/paritytech/ink/pull/979 Since...

Reduce Wasm code bloat of emitting ink! events

6

Currently emitting ink! events is very costly with respect to Wasm file sizes. The Wasm file size bloat primarily stems from the fact that upon emitting an event we first...

Pass large environmental ink! types by reference

Below is a list of isolated actionable items that may reduce the Wasm file size of certain ink! smart contracts if applied correctly and thoroughly throughout the ink! codebase and...

Currently ink! messages and constructors are required to be `Sized` and `scale::Decode`. This means that ink! messages and constructors that take simple references are not allowed, e.g.: ```rust #[ink(message)] fn...

# Spread allocate constructor syntax sugar ## Motivation With #961 it will become common to define ink! constructors in a way to allow for storage facilities that require initialization using...

The https://github.com/paritytech/ink/pull/665 PR introduces some new `is_result_type!` utility macro to check at compile time whether some type is a `Result` using the Rust type system. This means that we can...

Currently we only have a single passing UI test for ink! chain extensions. This is nowhere near where we want to be with respect of user facing tests. Ideally we...

We currently perform a heap allocation every time we use `ink_env::debug_print` or `ink_env::debug_println` macros. This is due to the usage of `format!` macro that constructs an instance of `String`: https://paritytech.github.io/ink/src/ink_env/lib.rs.html#141...

A new world: Reimplementation of the off-chain environment

To make it short and precise: Our off-chain environment is not more than a first attempt to get off-chain testing for smart contracts. Its design and implementation has never been...
