pub struct DecoyInfo {
    pub mixable: usize,
    pub not_mixable: usize,
    pub min_decoys: usize,
    pub max_decoys: usize,
}
Expand description

A struct holding information about the inputs and their decoys. This data can vary by block so this data needs to be retrieved after every change in the blockchain.

This data does not need to be refreshed if one of these are true:

  • The input amounts are ALL 0 (RCT)
  • The top block hash is the same as when this data was retrieved (the blockchain state is unchanged).

Fields§

§mixable: usize

The number of inputs that have enough outputs on the chain to mix with.

§not_mixable: usize

The number of inputs that don’t have enough outputs on the chain to mix with.

§min_decoys: usize

The minimum amount of decoys used in the transaction.

§max_decoys: usize

The maximum amount of decoys used in the transaction.

Implementations§

source§

impl DecoyInfo

source

pub fn new( inputs: &[Input], outputs_with_amount: impl Fn(u64) -> usize, hf: &HardFork, ) -> Result<DecoyInfo, TransactionError>

Creates a new DecoyInfo struct relating to the passed in inputs, This is only needed from hf 2 onwards.

outputs_with_amount is a list of the amount of outputs currently on the chain with the same amount as the inputs amount at the same index. For RCT inputs it instead should be None.

So:

amount_outs_on_chain(inputs[X]) == outputs_with_amount[X]

Do not rely on this function to do consensus checks!
