- Error cases description
// Parse a Redis response as a vector of Redis values // Redis response can be a vector of results or an error returned from redis +// Returns: +// - Ok(Vec<redis::Value>) if the response is an array +// - Err(FalkorDBError) containing the original Redis error if the response is a server error +// - Err(FalkorDBError::ParsingArray) for other invalid responses +// +// Example: +// ``` +// let response = redis_response_as_vec(value)?; +// for item in response { +// // Process each item +// } +// ```

135-139: LGTM! Clean implementation of error conversion.
The From trait implementation correctly maps Redis errors to FalkorDBError::RedisError, which aligns with the PR objective of passing Redis errors upstream instead of using generic errors.
135-139: Verify consistent error handling across the codebase.
Let's ensure this new error conversion is being used consistently and that we're not still using generic errors for Redis errors elsewhere.
✅ Verification successful
Let me analyze the Redis error handling patterns from the output. I can see three files with Redis error handling:
src/error/mod.rs: Contains the newFromimplementationsrc/connection/mod.rs: Has a custommap_redis_errfunctionsrc/parser/mod.rs: Has mixed error handling with both Redis errors and parsing errors
Let me verify if there are any other Redis-related error conversions or handling:
Redis error handling is consistent but could be simplified
The codebase shows a mixed pattern of Redis error handling:
- There's a dedicated
map_redis_errfunction insrc/connection/mod.rsthat provides specialized handling for connection-related Redis errors - The new
From<redis::RedisError>implementation insrc/error/mod.rsprovides a simpler conversion - Direct error conversions are used in various places (e.g., in
client/modules)
While the error handling is technically consistent (all Redis errors are properly captured), it could be simplified:
- The
map_redis_errfunction inconnection/mod.rsprovides more specific error mapping that's not available through the genericFromimplementation - Multiple modules directly convert Redis errors to
FalkorDBError::RedisErrorwhen they could use theFromimplementation - No instances found of Redis errors being improperly handled or escaping the error boundary
Recommendation: Consider consolidating the specialized error mapping from map_redis_err into the From<redis::RedisError> implementation to provide a single, consistent way to handle Redis errors throughout the codebase.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Check for potential inconsistent Redis error handling
# Look for direct Redis error handling that might not use the new From implementation
rg -l "redis::RedisError" | while read -r file; do
echo "=== Checking $file for Redis error handling ==="
rg -A 3 "redis::RedisError|FalkorDBError::ParsingArray|FalkorDBError::RedisError" "$file"
done
# Look for potential places where we might still be using ParsingArray for Redis errors
rg -A 3 "ParsingArray.*redis"
Length of output: 2078
Script:
#!/bin/bash

97-104: LGTM! Implementation aligns with PR objectives
The function correctly handles both successful array responses and server errors, properly propagating Redis errors upstream instead of wrapping them in a generic error type. This aligns well with the PR's objective of improving error granularity.
169-172: LGTM! Good refactoring
The changes improve code maintainability by leveraging the redis_value_as_typed_string helper function while maintaining proper error handling. The existing test coverage ensures the modification is safe.
