constructor

new Transfer(
    currentServiceId: number & WithBytesRepresentation<4> & WithOpaque<
        "ServiceId[u32]",
    >,
    partialState: PartialState,
): Transfer
Parameters
- currentServiceId: number & WithBytesRepresentation<4> & WithOpaque<"ServiceId[u32]">
- partialState: PartialState
Returns Transfer

Properties

basicGasCost

basicGasCost:
| number & WithBytesRepresentation<4> & WithOpaque<"SmallGas[U32]">
| ((regs: HostCallRegisters) => Gas) = ...

g = 10 + t

t has positive value, only when status of a transfer is OK 0 otherwise

Pre0.7.2: g = 10 + ω9

`Readonly`currentServiceId

currentServiceId: number & WithBytesRepresentation<4> & WithOpaque<
"ServiceId[u32]",
>

Currently executing service id.

index

index: number & WithBytesRepresentation<4> & WithOpaque<"HostCallIndex[U32]"> = ...

Index of that host call (i.e. what PVM invokes via ecalli)

tracedRegisters

tracedRegisters: (number & WithOpaque<"register index">)[] = ...

Input&Output registers that we should add to tracing log.

Methods

execute

execute(
    gas: IGasCounter,
    regs: HostCallRegisters,
    memory: HostCallMemory,
): Promise<PvmExecution | undefined>
Actually execute the host call.

NOTE the call is ALLOWED and expected to modify registers and memory.
Parameters
- gas: IGasCounter
- regs: HostCallRegisters
- memory: HostCallMemory
Returns Promise<PvmExecution | undefined>
