Crate zksync_vm2

High-Performance ZKsync Era VM

This crate provides high-performance VirtualMachine for ZKsync Era.

Re-exports

• pub use zksync_vm2_interface as interface;

Modules

• addressing_modes
  Addressing modes supported by EraVM.
• testonly
  Test-only tools for EraVM.

Structs

• FatPointer
  Fat pointer to a heap location.
• Instruction
  Single EraVM instruction (an opcode + Arguments).
• ModeRequirements
  VM execution mode requirements (kernel only, not in static call) that can be placed on instructions.
• Program
  Compiled EraVM bytecode.
• Settings
  VirtualMachine settings.
• Snapshot
  Opaque snapshot of a WorldDiff output by its eponymous method. Can be provided to WorldDiff::events_after() etc. to get data after the snapshot was created.
• StorageChange
  Change in a single storage slot.
• VirtualMachine
  High-performance out-of-circuit EraVM implementation.
• WorldDiff
  Pending modifications to the global state that are executed at the end of a block. In other words, side effects.

Enums

• ExecutionEnd
  VM stop reason returned from VirtualMachine::run().
• Predicate
  Predicate for an instruction. Encoded so that comparing it to flags is efficient.

Traits

• StorageInterface
  VM storage access operations.
• World
  Encapsulates VM interaction with the external world. This includes VM storage and decomitting (loading) bytecodes for execution.
