fix: resolve all MoonBit compiler warnings#4
Conversation
WalkthroughIntroduces a generated Quaternion library module with public types, methods, and trait impls; refactors error handling in quaternion constructors and normalize_mut to raise QuatError; adjusts array mapping in from_xyzw_array; updates tests to try?-style and inspect(...); and formats a function signature in euler.mbt.

🔇 Additional comments (18)
src/lib/lib.mbti (6)
1-2: File header looks good.The auto-generated header correctly identifies this as a generated file and includes the package declaration.
5-8: Error handling for array-based constructors is appropriate.The functions correctly declare that they can raise
QuatErrorwhen invalid input is provided.
16-16: Appropriate use ofsuberrorfor error handling.Using
suberrorinstead of a type alias is the correct approach for error handling in MoonBit.
19-24: Quaternion struct definition is well-structured.The mutable fields allow for efficient in-place operations while maintaining a clear API surface.
35-35:normalize_mutcorrectly declares error handling.The function appropriately raises
QuatErrorwhen attempting to normalize a zero-length quaternion.
48-54: Comprehensive trait implementations.All necessary traits for arithmetic operations, equality comparison, and display are properly implemented.
src/lib/euler.mbt (1)
3-7: Trailing comma addition is consistent with MoonBit style.The added trailing comma after the
zparameter follows MoonBit's formatting conventions and resolves the compiler warning.src/lib/quaternion_test.mbt (4)
1-5: Updated to modern MoonBit test syntax.The function-style
inspect(...)replaces the deprecated macro syntax correctly.
274-278: Proper error handling withtry?pattern.The migration from suffix-style error propagation to prefix-style
try?is correctly implemented and aligns with modern MoonBit error handling conventions.
282-286: Error case testing is comprehensive.Tests correctly verify that invalid array lengths raise errors as expected.
304-309: Thorough testing of normalization edge cases.The test properly handles both the success case with
unwrap()and the error case for zero-length quaternions.src/lib/quaternion.mbt (7)
24-29: Documentation example correctly updated.The example now uses the proper method name
to_wxyzand modern syntax.
142-146: Correct replacement of deprecatedor_default()method.The migration to
unwrap_or_default()properly addresses the compiler warning.
409-411: Proper replacement of deprecatedor()method.The change from
or()tounwrap_or()correctly resolves the compiler warning.
678-679: Appropriate error type declaration.Using
suberrorinstead of the deprecatedtype!correctly addresses the compiler warning.
681-686: Proper error handling for array validation.The function correctly validates array length and raises a descriptive error.
689-694: Verify the XYZW array mapping logic.The mapping from XYZW array format correctly places
wfrom index 3 and x, y, z from indices 0, 1, 2 respectively.
706-713: Excellent error handling for zero-length normalization.The function properly raises an error when attempting to normalize a zero-length quaternion, preventing undefined behavior.

In src/lib/quaternion.mbt around line 10, remove the empty comment line (a stray
blank comment artifact) so the file no longer contains that empty comment;
update the file by deleting that blank line and ensure surrounding comment
