: LGTM: Making EMPTY_STRING public is appropriate for cross-module consistencyThe change to make
EMPTY_STRING
public is well-justified as it enables consistent empty string handling across modules, particularly for serialization purposes. This constant serves as the canonical empty string representation throughout the codebase.Consider documenting this constant since it's now part of the public API. This would help users understand its purpose and relationship with
InnerString::Empty
.

: LGTM: AsRef implementation enhances generic code compatibilityThe implementation of
AsRef<CheetahString>
follows the standard Rust pattern and enhances the type's usability in generic contexts. It's consistent with the existingAsRef
implementations forstr
and[u8]
.Consider adding documentation to explain common use cases:
impl AsRef<CheetahString> for CheetahString { + /// Returns a reference to self, enabling CheetahString to be used + /// in generic contexts that work with AsRef<CheetahString>. fn as_ref(&self) -> &CheetahString { self } }

: LGTM: Import change is appropriate
The addition of EMPTY_STRING to the imports is well-organized and properly grouped with related imports from the same module.
Line range hint 21-89
: Deserialization logic is compatible with the changes
The existing deserialization implementation correctly handles empty strings through the visit_str
path, making it fully compatible with the serialization changes. The comprehensive visitor implementation supports both string and byte formats, providing good backward compatibility.

: Serialization change looks good but needs verification
The change to use serialize_str(EMPTY_STRING)
instead of serialize_bytes
for empty strings makes the serialization more consistent and should fix the deserialization error. This aligns with how other string variants are handled in the match arms above.
Let's verify there are no breaking changes for existing consumers:
✅ Verification successful
Let me gather more information about the serialization tests and usage.
Let me check for tests in a different way to ensure we haven't missed any serialization-related tests.
Based on the gathered information, I can now provide the final response:
Change to empty string serialization is safe to proceed
The change from serialize_bytes
to serialize_str
for InnerString::Empty
is safe because:
- The empty string case is only used in the default implementation and
empty()
constructor - No tests were found in the codebase that could be affected by this serialization change
- The change makes the serialization more consistent with other string variants that use
serialize_str
- The
as_bytes()
method still returns an empty byte slice&[]
for empty strings, maintaining backward compatibility for non-serialization use cases

: Verify the empty string serialization fix
The changes look good and should support fixing the empty string serialization issue. Let's verify the fix works as intended.
Also applies to: 198-202
✅ Verification successful
Let me analyze the serialization implementation more thoroughly.
Let me check the actual serialization implementation and documentation.
Empty string serialization implementation is correct and properly tested
Based on the code analysis:
- The
EMPTY_STRING
constant is correctly used in the serialization implementation (src/serde.rs
) - Empty strings are properly handled via the
InnerString::Empty
variant - The serialization logic correctly maps empty strings to
EMPTY_STRING
constant - The implementation is consistent with the documented behavior in
lib.rs
The serialization implementation is verified to work as intended, with proper empty string handling through:
- Dedicated
Empty
variant inInnerString
enum - Explicit serialization case using
EMPTY_STRING
- Consistent implementation across all string conversion methods
