Storage Macros

Procedural macros helper for interacting with cw-storage-plus and cosmwasm-storage.

Current features

Index List Impl Macros

Auto generate IndexList impl for your indexes struct.

index_list_impl(T) will generate impl IndexList<T> for struct T below the macro's call.

IndexList, Index imports from cw-storage-plus are also required.

#[derive(Serialize, Deserialize, Clone, Debug, PartialEq)]
struct TestStruct {
    id: u64,
    id2: u32,
    addr: Addr,
}

#[index_list_impl(TestStruct)] // <- Add this line right here,.
struct TestIndexes<'a> {
    id: MultiIndex<'a, (U32Key, Vec<u8>), TestStruct>,
    addr: UniqueIndex<'a, Addr, TestStruct>,
}

StorageKey, Primary Key And Prefixer Impl Deive Macros

Auto generate PrimaryKey and Prefixer impl for owned and reference variants, as_bytes and from_slice impl.

StorageKey will generate

• impl PrimaryKey<'_> for T
• impl<'a> PrimaryKey<'a> for &'a T
• impl Prefixer<'_> for T
• impl<'a> Prefixer<'a> for &'a T
• pub fn as_bytes(&self) -> &[u8]
• pub fn from_slice(b: &[u8]) -> T

for enum T below the macro's call.

PrimaryKey, Prefixer imports from cw-storage-plus are also required.

#[derive(Clone, Copy, StorageKey)] // <- Add the derive macro here.
enum TestEnum {
    G,
    F,
}
