Struct EvmContext

pub struct EvmContext<'a> {
    pub memory: &'a mut SharedMemory,
    pub contract: &'a mut Contract,
    pub gas: &'a mut Gas,
    pub host: &'a mut dyn HostExt,
    pub next_action: &'a mut InterpreterAction,
    pub return_data: &'a [u8],
    pub func_stack: &'a mut FunctionStack,
    pub is_static: bool,
    pub is_eof_init: bool,
    /* private fields */
}

The EVM bytecode compiler runtime context.

This is a simple wrapper around the interpreter’s resources, allowing the compiled function to access the memory, contract, gas, host, and other resources.

Fields

memory: &'a mut SharedMemory

The memory.

contract: &'a mut Contract

Contract information and call data.

gas: &'a mut Gas

The gas.

host: &'a mut dyn HostExt

The host.

next_action: &'a mut InterpreterAction

The return action.

return_data: &'a [u8]

The return data.

func_stack: &'a mut FunctionStack

The function stack.

is_static: bool

Whether the context is static.

is_eof_init: bool

Whether the context is EOF init.

Implementations

impl<'a> EvmContext<'a>

pub fn from_interpreter( interpreter: &'a mut Interpreter, host: &'a mut dyn HostExt, ) -> Self

Creates a new context from an interpreter.

pub fn from_interpreter_with_stack<'b: 'a>( interpreter: &'a mut Interpreter, host: &'b mut dyn HostExt, ) -> (Self, &'a mut EvmStack, &'a mut usize)

Creates a new context from an interpreter.

pub fn to_interpreter(&self, stack: Stack) -> Interpreter

Creates a new interpreter by cloning the context.

Trait Implementations

impl Debug for EvmContext<'_>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
