Module chainspec 

Chain spec parser that pre-populates the genesis alloc with ArbOS state when the spec declares config.arbitrum.InitialArbOSVersion but does not include the ArbOS state account in the alloc.

Structs

ArbChainSpecParser

Functions

allow_debug_precompiles

Returns the AllowDebugPrecompiles flag declared in the chain spec’s config.arbitrum section, defaulting to false.

compute_arbos_alloc

Run genesis::initialize_arbos_state in a scratch in-memory state and dump the resulting account/storage map. Returns one entry per account touched (the ArbOS state address plus all genesis precompile markers).

compute_arbos_alloc_with_config

Run genesis::initialize_arbos_state in a scratch in-memory state using a caller-supplied serialized chain config and initial L1 base fee.

serialize_chain_config_go_style

Serialize a chain-config JSON object the way Go’s json.Marshal of params.ChainConfig would. Field order, address casing, and which fields are emitted (vs. dropped via omitempty) match Go’s encoder so the resulting bytes are byte-identical to what ArbOS init stores in the chain_config subspace at genesis.
