Expand description

Representation of a single transformation ocurring during execution.

Note that all arithmetic variants of Transform are commutative which means that a given collection of them can be executed in any order to produce the same end result.

Variants

Identity

An identity transformation that does not modify a value in the global state.

Created as part of a read from the global state.

Write(StoredValue)

Tuple Fields

Writes a new value in the global state.

AddInt32(i32)

Tuple Fields

0: i32

A wrapping addition of an i32 to an existing numeric value (not necessarily an i32) in the global state.

AddUInt64(u64)

Tuple Fields

0: u64

A wrapping addition of a u64 to an existing numeric value (not necessarily an u64) in the global state.

AddUInt128(U128)

Tuple Fields

0: U128

A wrapping addition of a U128 to an existing numeric value (not necessarily an U128) in the global state.

AddUInt256(U256)

Tuple Fields

0: U256

A wrapping addition of a U256 to an existing numeric value (not necessarily an U256) in the global state.

AddUInt512(U512)

Tuple Fields

0: U512

A wrapping addition of a U512 to an existing numeric value (not necessarily an U512) in the global state.

AddKeys(NamedKeys)

Tuple Fields

Adds new named keys to an existing entry in the global state.

This transform assumes that the existing stored value is either an Account or a Contract.

Failure(Error)

Tuple Fields

0: Error

Represents the case where applying a transform would cause an error.

Implementations

Applies the transformation on a specified stored value instance.

This method produces a new StoredValue instance based on the Transform variant.
