The BoundTypes library helps you to seamlessly design and set rules for data types in your code, making it safer and more reliable.
To install BoundTypes, simply use the Julia package manager:
] add BoundTypesDemonstrate value validation during object construction:
using BoundTypes
struct CoinInfo
asset::StringPattern{String,pattern"^([A-Z]+)$"}
network::StringMinLength{String,3}
address::StringFixedLength{StringPattern{String,pattern"^0x([abcdef0-9]+)$"},40}
deposit_fee::NumberNonNegative{Float64}
withdrawal_fee::NumberPositive{Float64}
end
julia> CoinInfo("ETH", "Ethereum", "0xc0ffee254729296a45a3885639ac7e10f9d549", 0.0, 0.01)
CoinInfo("ETH", "Ethereum", "0xc0ffee254729296a45a3885639ac7e10f9d549", 0.0, 0.01)
julia> CoinInfo("eth!", "EM", "0xc0FFE12A2", -1.0, 0.0)
Wrong value: "eth!" must match to regex pattern ^([A-Z]+)$.Using BoundTypes for serialization and deserialization with Serde.jl:
using Serde
using BoundTypes
struct User
name::StringMinLength{String,5}
pass::StringMaxLength{StringMinLength{StringPattern{String,pattern"^[\w@]+$"},10},20}
end
julia> Serde.deser_json(User, """ {"name": "Julia", "pass": "MyBestP@ssw0rdEv3r"} """)
User("Julia", "MyBestP@ssw0rdEv3r")
julia> Serde.deser_json(User, """ {"name": "Julia", "pass": "2ShrtP@ss"} """)
Wrong value: length of the "2ShrtP@ss" must be at least 10 characters (9).
julia> Serde.deser_json(User, """ {"name": "Julia", "pass": "Bad/Password#"} """)
Wrong value: "Bad/Password#" must match to regex pattern ^[\w@]+$.
julia> Serde.to_json(User("Julia", "MyBestP@ssw0rdEv3r"))
"{\"name\":\"Julia\",\"pass\":\"MyBestP@ssw0rdEv3r\"}"Contributions to BoundTypes are welcome! If you encounter a bug, have a feature request, or would like to contribute code, please open an issue or a pull request on GitHub.
