Function regex_dict_str 

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

Applies regular expression patterns to categorical array values against string patterns.

Evaluates regex patterns from the string array against dictionary-resolved strings from the categorical array, producing a boolean array indicating matches.

Parameters

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

Type Parameters

• U: Integer type for categorical array indices
• T: Integer type for pattern 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.
