Enum Instruction 

pub enum Instruction {
    Push(String),
    Store {
        slot: String,
    },
    Load {
        slot: String,
    },
    Call {
        target: String,
    },
    Log {
        topic: String,
    },
    Add,
    Sub,
    RequireGte {
        reason: String,
    },
    Transfer {
        to: String,
    },
    Revert {
        reason: String,
    },
}

High-level instruction that the scenario compiler emits. Each maps to one or more low-level opcodes in the trace.

Variants

Push(String)

Push a literal value onto the stack.

Store

Store top-of-stack into a named storage slot.

Fields

slot: String

Load

Load a named storage slot onto the stack.

Fields

slot: String

Call

Call a named function (creates a call frame in the trace).

Fields

target: String

Log

Emit a log event with a topic.

Fields

topic: String

Add

Arithmetic: add top two stack values.

Sub

Arithmetic: subtract top two stack values (a - b where a is deeper).

RequireGte

Compare top two stack values; revert with reason if a < b.

Fields

reason: String

Transfer

Transfer value externally (external CALL with value).

Fields

to: String

Revert

Explicitly revert with a reason.

Fields

reason: String
