Crate sputnikvm [−] [src]
SputnikVM implementation, traits and structs
Lifecycle
A VM can be started given a Context and a BlockHeader. The
user can then fire or step to run it. Those functions would
only fail if it needs some information (accounts in the current
block, or block hashes of previous blocks). If this happens, one
can use the function commit_account and commit_blockhash to
commit those information to the VM, and fire or step again
until it succeeds. The current VM status can always be obtained
using the status function.
