Struct EvmContext 

pub struct EvmContext<'a> {
    pub memory: &'a mut SharedMemory,
    pub input: &'a mut InputsImpl,
    pub gas: &'a mut Gas,
    pub host: &'a mut dyn HostExt,
    pub next_action: &'a mut Option<InterpreterAction>,
    pub return_data: &'a [u8],
    pub is_static: 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, input, gas, host, and other resources.

Safety

This struct uses #[repr(C)] to ensure a stable field layout since the JIT compiler generates code that accesses fields by offset using offset_of!.

Fields

memory: &'a mut SharedMemory

The memory.

input: &'a mut InputsImpl

Input information (target address, caller, input data, call value).

gas: &'a mut Gas

The gas.

host: &'a mut dyn HostExt

The host.

next_action: &'a mut Option<InterpreterAction>

The return action.

return_data: &'a [u8]

The return data.

is_static: bool

Whether the context is static.

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.

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.
