v0.23.0

What's Changed

Breaking

• #263 Removes the TwosComplement trait in favor of WrappingNeg.

The following demonstrates the breaking change. While this example code uses the I8 type, the same logic may be applied to the I16, I32, I64, I128, and I256 types.

Before:

let my_i8 = i8::zero();
let twos_complement = my_i8.twos_complement();

After:

let my_i8 = i8::zero();
let wrapping_neg = my_i8.wrapping_neg();

• #272 The From implementation for all signed integers to their respective unsigned integer has been removed. The TryFrom implementation has been added in its place.

Before:

let my_i8: I8 = I8::from(1u8);

After:

let my_i8: I8 = I8::try_from(1u8).unwrap();

• #273 The neg_from implementation for all signed integers has been removed. The neg_try_from() implementation has been added in its place.

The following demonstrates the breaking change. While this example code uses the I8 type, the same logic may be applied to the I16, I32, I64, I128, and I256 types.

Before:

let my_negative_i8: I8 = I8::neg_from(1u8);

After:

let my_negative_i8: I8 = I8::neg_try_from(1u8).unwrap();

• #278 Deprecates the Fixed Point number library. The Fixed Point number library is no longer available.

Added

• #259 Adds a new upgradability library, including associated tests and documentation.
• #265 Adds the SetMetadataEvent and emits SetMetadataEvent when the _set_metadata() function is called.
• #270 Adds OrdEq functionality to Signed Integers.
• #272 Adds the TryFrom implementation from signed integers to unsigned integers.

Changed

• #265 Enables the metadata events now that the Rust SDK supports wrapped heap types.
• #269 Hashes the string "admin" and with the bits of an Identity when creating a storage slot to storage an admin in the Admin Library.
• #276 Prepares for v0.23.0 release.
• #278 Deprecates the Fixed Point number library.

Fixed

• #258 Fixes incorrect instructions on how to run tests in README and docs hub.
• #262 Fixes incorrect ordering comparison for IFP64, IFP128 and IFP256.
• #263 Fixes I256's returned bits.
• #263 Fixes I128 and I256's zero or "indent" value.
• #268 Fixes subtraction involving negative numbers for I8, I16, I32, I64, I128, and I256.
• #272 Fixes From implementations for Signed Integers with TryFrom.
• #273 Fixes negative from implementations for Signed Integers.
• #274 Fixes the swap_configurables() function to correctly handle the case where the bytecode is too large to fit in the buffer.
• #275 Fixes an infinite loop in the Bytecode root library's _compute_bytecode_root() function.
