Module forest_filecoin::shim::fvm_latest::syscalls

Structs

• Context
  The syscall context. Allows syscalls to access the [Kernel] and the actor’s memory.
• Linker
  A “linker” for exposing syscalls to wasm modules.
• Memory
  Represents a Wasm memory. All methods are inexpensive and time-bounded, regardless of the inputs. It’s usually not necessary to explicitly account for the gas costs of calling these methods a small (< 5) constant number of times while handling a syscall.

Enums

• Abort
  Represents an actor “abort”. Returning an Abort from a syscall will cause the currently running actor to exit and may cause part or all of the actor call stack to unwind.
• ControlFlow
  ControlFlow is a general-purpose enum for returning a control-flow decision from a syscall.

Traits

• IntoControlFlow
  The helper trait used by Syscall to convert kernel results with execution errors into results that can be handled by the wasm vm. See the documentation on Syscall for details.
• Syscall
  A Syscall is a function in the form fn(Context<'_, K>, I...) -> R where:
