Struct StepRecord 

pub struct StepRecord {
    pub pc: u64,
    pub op: u8,
    pub gas: u64,
    pub gas_cost: u64,
    pub depth: u64,
    pub error: Option<String>,
    pub memory: Option<Bytes>,

}

One step as a producer appends it with StepTable::append: its plain fields, and the state that changed since the step before.

Fields

pc: u64

op: u8

gas: u64

gas_cost: u64

The cost as the tracer reports it; see TraceStep::gas_cost.

depth: u64

error: Option<String>

memory: Option<Bytes>

The memory the step starts with, in full. None leaves it to the frame being recorded with StepTable::write_memory, or keeps the previous step’s when none is.

storage: Option<Arc<BTreeMap<String, String>>>

The storage the backend reports for the step; None keeps the previous step’s.

storage_diff: Option<BTreeMap<String, StorageChange>>

The slots the step changed.

transient_storage: Option<BTreeMap<String, String>>

The transient slots the step read or wrote, with their value after it.

return_data: Option<Arc<str>>

The return data buffer the step starts with, as unprefixed hex; empty for an empty buffer, and None keeps the previous step’s.
