Module forest_filecoin::shim::fvm_latest::kernel

Modules§

default
filecoin
prelude
Import this module (with a glob) if you’re implementing a kernel, especially if you want to use ambassador to delegate the implementation.

Block
BlockRegistry
A registry of open blocks (per-kernel). Think “file descriptor” table. At the moment, there’s no way to close/remove a block from this table.
BlockStat
CallResult
SyscallError
Represents an error from a syscall. It can optionally contain a syscall-advised exit code for the kind of error that was raised. We may want to add an optional source error here.

ExecutionError
SupportedHashes
Codes and hashers supported by FVM. You can use this hash directly inside of your actor, but it will very likely be more performant with the hash syscall

ActorOps
Actors operations whose scope of action is actors other than the calling actor. The calling actor’s state may be consulted to resolve some.
ClassifyResult
Context
The FVM’s equivalent of anyhow::Context. This is intentionally only implemented on ExecutionError and Result<T, ExecutionError> so anyhow::Context can be imported at the same time.
CryptoOps
Cryptographic primitives provided by the kernel.
DebugOps
Debugging APIs.
EventOps
Eventing APIs.
IpldBlockOps
The IPLD subset of the kernel.
Kernel
The “kernel” implements the FVM interface as presented to the actors. It:
MessageOps
Accessors to query attributes of the incoming message.
NetworkOps
Network-related operations.
RandomnessOps
Randomness queries.
SelfOps
Actor state access and manipulation. Depends on BlockOps to read and write blocks in the state tree.
SendOps
The actor calling operations.
SyscallHandler
UpgradeOps
The actor upgrade operations.

BlockId
Blocks in the block registry are addressed by an ordinal, starting from 1 (FIRST_ID). The zero value is reserved to mean “no data”, such as when actor invocations receive or return no data.
Result
Execution result.
