This API is shared between the builders and the CoreVM service itself.

Modules

flags

Host-call flags.

fs

CoreVM FS that uses preimage store as a backend.

Structs

Arg

Command line argument.

AudioMode

Audio monitor output mode.

ConsoleChunk

A chunk of console output.

ConsoleChunks

Several chunks of console output.

CoreVmExtrinsics

CoreVM-specific extrinsics.

CoreVmOutput

CoreVM-specific work output.

CoreVmPayload

CoreVM-specific work payload.

ExecEnv

Guest execution environment.

InputChunk

Input chunk.

InputStreams

A set of input streams.

KernelFd

In-kernel file descriptor state.

KernelState

The state of the Linux kernel syscall layer.

LenAndSourceOutcome

The base types for outcomes that encodes Option<(u32, u32)>, that contains length and source, as a single 64-bit value. None is encoded as u64::MAX, and thus length must be less than u32::MAX.

MessageQueue

Message queue in service storage.

OutgoingServiceMessage

OutputBuffers

CoreVM output stream buffers.

PageInfo

Memory page metadata.

PageNum

RecvHostMessageOutcome

The return type of recv_host_message host-call (message length and source).

RecvMessageOutcome

The return type of recv_message host-call (message length and source).

RecvTransactionOutcome

The return type of recv_transaction host-call (payload length and source).

ServiceMessage

A message from another service.

VideoMode

Video monitor output mode.

VideoModeOptions

Optional video mode parameters.

VmOutput

The specification of the VM’s output data.

VmSpec

Same as CoreVmOutput but only includes the data necessary to continue program execution.

VmState

Inner VM state.

Enums

AudioSampleFormat

The format of the samples emitted via yield_audio_samples.

CoreVmInstruction

Instruction to send to the CoreVM service.

InputVideoFrameFormat

The format of the input video frames accesed via read_video_frame.

Outcome

The result code returned by CoreVM service.

OutputStream

Output stream identifier.

StorageKey

Storage keys used by CoreVM.

VideoFrameFormat

The format of the frames emitted via [yield_video_frame].

Constants

Type Aliases

GuestId
