CLType

Casper types, i.e. types which can be stored and manipulated by smart contracts. Provides a description of the underlying data type of a CLValue.

    `Bool`
`I32`
`I64`
`U8`
`U32`
`U64`
`U128`
`U256`
`U512`
`Unit`
`String`

`PublicKey`
`Any`
  • Option Option of a CLType.

  • List Variable-length list of a single CLType (comparable to a Vec).

  • ByteArray Fixed-length list of a single CLType (comparable to a Rust array).

  • Result Result with Ok and Err variants of CLType's.

  • Map Map with keys of a single CLType and values of a single CLType.

  • Tuple1 1-ary tuple of a CLType.

  • Tuple2 2-ary tuple of CLTypes.

  • Tuple3 3-ary tuple of CLTypes.

CLValue‚Äč

A Casper value, i.e. a value which can be stored and manipulated by smart contracts. It holds the underlying data as a type-erased, serialized Vec<u8> and also holds the CLType of the underlying data as a separate member. The parsed field, representing the original value, is a convenience only available when a CLValue is encoded to JSON, and can always be set to null if preferred.
