v2.14.0-rc.0

Cairo compiler.

v2.13.1

What's Changed

• Made all maps that may have a large number of elements be hash-maps. #8579

Full Changelog: v2.13.0...v2.13.1

v2.13.0

Major Features

• Added item level inline macros.
• Support for more complex match, if let and while let
  • Includes recursive variants, structs, tuples, and numeric values.
• Added ByteSpan in corelib.

Breaking Changes

• Global impls
  • impls defined near the type are always considered when solving an impl - even if the type doesn't exist.
  • This causes a breakage where Into::into and TryInto::try_into calls that weren't actually required causes inference errors.
• Made Iterator::fold be consuming. #8214
• Made let x = y; move non-copy y. #8521
• Changed bytearray pending word into Byte31Index. #8516
  • Should only affect users that use old edition and accessed the internal fields of ByteArray.

Bug Fixes

• Handling zero-sized generics. #7990
• Properly recognising when a closure is not fully concrete. #7987
• Const-folded pop from empty arrays and spans keep the expected var. by @orizi in #8117
• Fix const reported as unused. #8139
• Added dignostics for having a starkware interface with a body. #8216
• Block tail expressions fully process attributes. #8257
• disallow named arguments in closures. #8278
• Not generating expressions of deref if not found. #8295
• added is_zero functions to extern consts list. #8360
• add diagnostic when use star causes cycles. #8463
• Expose Sum and Product traits. #8542

Other new features

• Add Nullable::deref_or_else. #8026
• feat(semantic): support allow(unused_variables) by @giladchase in #8289
• added inference for negative impls. #8339
• Implemented sub_pointers for Option. #8525
• Added support for override file location using path. by @orizi in #8557

Optimizations

Compiler runtime

• Less green lookups + string manip - direct usage of file content. #7966
• Made get_submodule query based instead of iteration based. #7980
• Removed location fetching when get_dummy_program_for_size_estimation. #7982
• Refactored Maps from CostTokenType to be defined once. #8021
• Changed CostTokenMap type to vec-map. #8023
• Creating metadata only once. #8019
• Updated salsa version.

Gas usage

• Improved ByteArray iteration.
• Improved ByteArray manipulation.
• Compute ByteArray sha256 via iterator. #8540

Code size

• Added common-expression-elimination optimization. #8217
• Const folding of matching on snapshots. #8377
• Using unwrap_syscall instead of simple unwrap where possible. #8561
