Struct CostEstimationHints 

pub struct CostEstimationHints {
    pub disabled: bool,
    pub expected_signatures: Vec<i32>,
}

Hints to improve cost estimation precision of a prepared transaction

Fields

disabled: bool

Disable cost estimation Default (not set) is false

Optional

expected_signatures: Vec<i32>

Details on the keys that will be used to sign the transaction (how many and of which type). Signature size impacts the cost of the transaction. If empty, the signature sizes will be approximated with threshold-many signatures (where threshold is defined in the PartyToParticipant of the external party), using keys in the order they are registered. Empty list is equivalent to not providing this field

Optional: can be empty

Implementations

impl CostEstimationHints

pub fn expected_signatures( &self, ) -> FilterMap<Cloned<Iter<'_, i32>>, fn(i32) -> Option<SigningAlgorithmSpec>>

Returns an iterator which yields the valid enum values contained in expected_signatures.

pub fn push_expected_signatures(&mut self, value: SigningAlgorithmSpec)

Appends the provided enum value to expected_signatures.
