Function regex_str_str 

pub fn regex_str_str<'a, T: Integer, U: Integer>(
    lhs: StringAVT<'a, T>,
    rhs: StringAVT<'a, U>,
) -> Result<BooleanArray<()>, KernelError>

Applies regular expression pattern matching between two string arrays.

Evaluates regex patterns from the right-hand string array against corresponding strings in the left-hand array, producing a boolean array indicating matches.

Parameters

• lhs: Source string array view tuple (StringArray, offset, length)
• rhs: Pattern string array view tuple (StringArray, offset, length)

Type Parameters

• T: Integer type for left array offsets
• U: Integer type for right array offsets

Returns

Result<BooleanArray<()>, KernelError> where true indicates pattern match.

Errors

Returns KernelError for invalid regular expression patterns.

Feature Gate

Requires the regex feature to be enabled.

Performance

• Regex compilation overhead amortised across bulk operations
• Pattern caching opportunities for repeated patterns
