Struct ShuffleResult 

pub struct ShuffleResult {
    pub ops: Vec<StackOp>,
    pub dup_count: usize,
    pub swap_count: usize,
    pub pop_count: usize,
}

Result of a shuffle operation.

Fields

ops: Vec<StackOp>

The sequence of operations to perform.

dup_count: usize

Number of DUP operations.

swap_count: usize

Number of SWAP operations.

pop_count: usize

Number of POP operations.

Implementations

impl ShuffleResult

pub fn new() -> ShuffleResult

Creates an empty shuffle result.

pub fn is_empty(&self) -> bool

Returns true if no operations are needed.

pub fn op_count(&self) -> usize

Returns the total number of operations.

pub fn estimated_gas(&self) -> u64

Estimated gas cost (DUP/SWAP = 3 gas each, POP = 2 gas).
