Spade 0.21.0

Added

• #1113 Support const generics inside struct and enum definitions
• #1140 Added named parameter support inside parenthesized argument lists (...)
• #1148 Added const type { ... } to create inline const generics that can be used as values
• #1152 Added gen match { ... } blocks
• #1162 then_some method on bool
• #1174 Added << and >> to const generics
• #1184 Implementations for Type Aliases
• #1194 Add memory language construct to build memories
• #1204 Added std::undef::unused() to the standard library and prelude,
  a function that returns an unconnected inverted signal (equivalent to port().1,
  but signals the design intent more clearly).
• #1235 Added Result type to stdlib
• #718 Allowed { ... } instead of $(...) for named argument lists

Fixed

• #1143 Made arrays render in the correct order in Surfer and test benches (their contents were reversed)
• #1150 Fix some rare panics in typeinference when constraints are resolved at the wrong time
• #1151 Fixed a bug where certain malformed items cause an ICE
• #1159 Fixed a bug where match expressions could miss si integer values
• #1163 Fixed an error message where uint would erroneously be printed as int
• #1191 Fixed ICE when defining pipeline method with no arguments besides self (no clock)
• #1195 Fixed parsing error when using named stages in pipeline lambdas
• #1226 Fix duplicate equation panic in test benches
• #712 Fixed generic substitution bug inside copy views.
• #712 Preluded core::marker::Copy that was accidentally left behind.
• #717 Fixed spurious linearity error when using as on inv values
• #717 tri is now actually !Data

Changed

• #1139 Made . correctly traverse through inv inside copy views
• #1140 Deprecated $(...) named argument list syntax
• #1141 inv wires now can appear inside enum variants.
• #1173 Deprecated >>> in favor of >>
• #1175 Improved set ergonomics by expanding it to work on inv wires inside arrays and tuples
• #1187 Updated cocotb to 2.1. If you use fancy cocotb features, this may cause breaking changes
• #1194 Deprecated std::mem::clocked_memory and associated elements
• #1213 Disallow consuming linear resources inside conditionals
• #1223 Allowed match expressions returning zero-sized values
• #1236 Register definitions inside pipelines may be written without an explicit clock signal (it will use the pipeline's clock signal)
• #1243 Deprecated std::mem::dp_bram in favor of std::mem::simple_dual_port_ram
• #1243 Deprecated std::mem::read_read_port
• #1243 Removed address width parameter from std::mem::fifo and enforced a power-of-two number of elements
• #712 Now copy views carry with them the data of inv wires.
• #712 Changed the signature of inv T::inspect to inspect(&self) -> &T.
• #715 Allowed inv values to be returned by if/else and match blocks to be connected from the outside (all arms receive the same value)
• #716 Made inv values interact gracefully with pattern matching.
