Enum essential_state_asm::Op

pub enum Op {
    Constraint(Constraint),
    StateSlots(StateSlots),
    KeyRange,
    KeyRangeExtern,
}

All operations available to state-read execution.

Variants

Constraint(Constraint)

All operations available to the constraint checker.

Note that this is a subset of the operations available to state read execution.

StateSlots(StateSlots)

Operations for controlling mutable state slots.

KeyRange

0x90

Read a range of values at each key from state starting at the key into state slots starting at the slot index.

The key is lexographically incremented for each value read. All keys are assumed to be the same length.

Returns the values onto the stack, followed by their indices.

Stack Input

[key_w0, ...key_wN, key_len, num_keys_to_read, slot_index]

KeyRangeExtern

0x91

Read a range of values at each key from external state starting at the key into state slots starting at the slot index.

The key is lexographically incremented for each value read.

The external state is at the ext address.

Returns the values onto the stack, followed by their indices.

Stack Input

[ext_w0, ext_w1, ext_w2, ext_w3, key_w0, ...key_wN, key_len, num_keys_to_read, slot_index]
