This pr intended to make generated enum items impl FromStr and Display and Into trait.
Usually an enum (in or not in trading) may have two different usecases: either for integer-compitible values (like Side/OrderType) or for string values (like Market). It's very kind to generate conversion helper for generated Rust enum types. Currently only From was impl for enum types.
FromStr trait
Consider a Market enum:
enum Market {
XSHE, XSHG,
}
A str to Market conversion was usually needed when dealing with external system.
Display trait
See above Market enum, a Display trait impl was helpful when converting to meaningful string representation for display or presentation purpose.
Into trait
As a reverse op of From, it is also helpful to get sensible storing data into DB or something similar.
