Struct grin_core::core::transaction::Input

pub struct Input {
    pub features: OutputFeatures,
    pub commit: Commitment,
}

A transaction input.

Primarily a reference to an output being spent by the transaction.

Fields

features: OutputFeatures

The features of the output being spent. We will check maturity for coinbase output.

commit: Commitment

The commit referencing the output being spent.

Methods

impl Input

The input for a transaction, which spends a pre-existing unspent output. The input commitment is a reproduction of the commitment of the output being spent. Input must also provide the original output features and the hash of the block the output originated from.

pub fn new(features: OutputFeatures, commit: Commitment) -> Input

Build a new input from the data required to identify and verify an output being spent.

pub fn commitment(&self) -> Commitment

The input commitment which partially identifies the output being spent. In the presence of a fork we need additional info to uniquely identify the output. Specifically the block hash (to correctly calculate lock_height for coinbase outputs).

pub fn is_coinbase(&self) -> bool

Is this a coinbase input?

pub fn is_plain(&self) -> bool

Is this a plain input?

Trait Implementations

impl DefaultHashable for Input

impl Writeable for Input

Implementation of Writeable for a transaction Input, defines how to write an Input as binary.
