**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** <!-- A clear and concise description of what the problem is. Ex. I'm always frustrated when [...] (This section helps Arrow developers understand the context and *why* for this feature, in addition to the *what*) --> The `Parser` has been impled for these arrow_array::types: https://docs.rs/arrow-cast/33.0.0/arrow_cast/parse/trait.Parser.html#foreign-impls Maybe we could impl `Parser` for more types, eg Decimal128 and Decimal256 and so on. Uniformly resolving the type interface can reduce much code. **Describe the solution you'd like** <!-- A clear and concise description of what you want to happen. --> Impl `Parser` for the types in https://docs.rs/arrow-array/33.0.0/arrow_array/types/index.html **Describe alternatives you've considered** <!-- A clear and concise description of any alternative solutions or features you've considered. --> This may be required to add more methods to `Parser`. For example, to impl Parser for Decinal we should add this: ```rust pub trait Parser: ArrowPrimitiveType { fn parse(string: &str) -> Option<Self::Native>; fn parse_formatted(string: &str, _format: &str) -> Option<Self::Native> { Self::parse(string) } /// add for Parse Decimal fn parse_with_parameter(string: &str, _precision: u8, _scale: i8) -> Option<Self::Native> { Self::parse(string) } } ``` Or consider making the parse function receive arbitrary arguments so that it can only need itself by `Parser`? **Additional context** <!-- Add any other context or screenshots about the feature request here. --> -- This is an automated message from the Apache Git Service.
