RethEvmFactory

reth_evm_ethereum::factory

Struct RethEvmFactory 

Source 
pub struct RethEvmFactory { /* private fields */ }
Expand description

Reth EVM factory.

With the jit feature, this wraps [JitEvmFactory] and owns the shared revmc backend. The backend is constructed for every node so runtime RPC controls can enable it later.

An EVM can execute JIT-compiled code only when all three gates are enabled: the binary was built with the jit feature, runtime compilation was enabled with --jit or the reth_jit RPC method, and the local EVM config selected JIT support with ConfigureEvm::with_jit_support.

Without the jit feature, this is a thin wrapper around [alloy_evm::EthEvmFactory].

Implementations§

Source§

impl RethEvmFactory

Source

pub fn new(backend: JitBackend) -> Self

Available on crate feature jit only.

Creates a new factory that owns the backend.

Source

pub fn new_with_metrics(backend: JitBackend, metrics: RevmcMetrics) -> Self

Available on crate feature jit only.

Creates a new factory that owns the backend and records metrics into the given handles.

Source

pub fn disabled() -> Self

Available on crate feature jit only.

Creates a RethEvmFactory with JIT support and compilation disabled.

Source

pub const fn backend(&self) -> &JitBackend

Available on crate feature jit only.

Returns a reference to the JIT backend.

Source

pub const fn set_jit_support(&mut self, enabled: bool)

Available on crate feature jit only.

Enables or disables local JIT support for subsequently created EVMs.

Enabling support only selects the JIT-capable EVM factory path. An EVM still requires the jit feature and runtime compilation enabled by --jit or reth_jit before it can execute JIT-compiled code.

Source

pub const fn jit_support_enabled(&self) -> bool

Available on crate feature jit only.

Returns whether subsequently created EVMs use the JIT-capable factory path.
