pub fn etch_foundry_artifact_or_create(
    cache: &mut EvmCache,

) -> DeployResult<EtchedContract>
Expand description

Deploy a Foundry artifact and copy its runtime bytecode to target, creating a default target account when it does not already exist.

Prefer etch_foundry_artifact for forked/live contract addresses whose storage, balance, or nonce should be preserved.

§Errors

Returns an error if the artifact cannot be loaded (see load_foundry_creation_code), if the deployment reverts or halts, or if copying the runtime bytecode to target fails, for example when the deployed contract has empty runtime bytecode (see FoundryArtifact::etch_or_create).

§Panics

Must run on a multi-thread tokio runtime; the deployment panics on a current-thread runtime when the fork DB attempts a synchronous RPC fetch.
