CW Ownable

Utility for controlling ownership of CosmWasm smart contracts.

How to use

Use the #[cw_ownable] macro to define your execute message:

```rust use cosmwasmschema::cwserde; use cwownable::{cwownable, Expiration};

[cw_ownable]

[cw_serde]

enum ExecuteMsg { Foo {}, Bar {}, } ```

The macro inserts a new variant, UpdateOwnership to the enum:

```rust

[cw_serde]

enum ExecuteMsg { UpdateOwnership(cw_ownable::Action), Foo {}, Bar {}, } ```

Where Action can be one of three:

• Propose to transfer the contract's ownership to another account
• Accept the proposed ownership transfer
• Renounce the ownership, permanently setting the contract's owner to vacant

Handle the messages using the update_ownership function provided by this crate:

```rust use cosmwasmstd::{entrypoint, DepsMut, Env, MessageInfo, Response}; use cwownable::{cwserde, update_ownership, OwnershipError};

[entry_point]

pub fn execute( deps: DepsMut, env: Env, info: MessageInfo, msg: ExecuteMsg, ) -> Result { match msg { ExecuteMsg::UpdateOwnership(action) => { update_ownership(deps, &env.block, &info.sender, action)?; } _ => unimplemneted!(), } Ok(Response::new()) } ```
