Struct cfx_executor::stack::FrameLocal

pub struct FrameLocal<'a> {
    pub space: Space,
    pub env: &'a Env,
    pub depth: usize,
    pub create_address: Option<Address>,
    pub origin: OriginInfo,
    pub substate: Substate,
    pub machine: &'a Machine,
    pub spec: &'a Spec,
    pub static_flag: bool,
}

FrameLocal represents the local data associated with a specific call frame during the execution of the Ethereum Virtual Machine (EVM). This data is local to the frame and is not visible to other frames in the execution stack.

Fields

space: Space

The space the current frame belongs.

env: &'a Env

A reference to environmental information relevant to the current execution, such as the block number and block author.

depth: usize

The depth of the current frame in the call stack.

create_address: Option<Address>

The address of the newly deployed contract, if the current frame is for contract creation.

origin: OriginInfo

The caller information for the current frame, including the caller, the original sender, etc.

substate: Substate

Collects changes produced during execution for post-execution logic such as collecting storage fees, and generating receipts.

machine: &'a Machine

All the necessities for executing EVM bytecode.

spec: &'a Spec

Activated hardfork features and the parameters that may be modified in hardfork

static_flag: bool

Enforce the static context of a call, as defined by EIP-214 (STATICCALL), ensuring that certain operations do not alter the state.

Implementations

impl<'a> FrameLocal<'a>

pub fn new( space: Space, env: &'a Env, machine: &'a Machine, spec: &'a Spec, depth: usize, origin: OriginInfo, substate: Substate, create_address: Option<Address>, static_flag: bool ) -> Self

pub fn make_vm_context<'b, 'c>( &'b mut self, resources: &'b mut RuntimeRes<'c> ) -> Context<'b>

Creates a Context for the current frame, which includes two distinct parts:

1. Local frame information - Specific to the current frame and not visible to others.
2. Runtime resources - Contains global information like the ledger state, accessible across frames.
