Struct BatchOutputs 

pub struct BatchOutputs { /* private fields */ }

The public outputs produced by the batch kernel.

This is the parsed, typed form of the kernel’s output stack.

Implementations

impl BatchOutputs

pub const INPUT_NOTES_COMMITMENT_WORD_IDX: usize = 0

The element index at which the input notes commitment word starts on the output stack.

pub const BATCH_NOTE_TREE_ROOT_WORD_IDX: usize = 4

The element index at which the batch note tree root word starts on the output stack.

pub const BATCH_EXPIRATION_BLOCK_NUM_ELEMENT_IDX: usize = 8

The element index at which the batch expiration block number is stored on the output stack.

pub fn new( input_notes_commitment: Word, batch_note_tree_root: Word, batch_expiration_block_num: BlockNumber, ) -> Self

Returns a new BatchOutputs instantiated from the provided data.

pub fn parse(stack: &StackOutputs) -> Result<Self, BatchOutputError>

Parses the batch kernel’s output stack into a BatchOutputs.

Errors

Returns BatchOutputError::OutputStackInvalid if:

• a required output word or element is missing from the stack;
• the cells following batch_expiration_block_num (positions 9..16) are not all zero.

Returns BatchOutputError::ExpirationBlockNumberTooLarge if batch_expiration_block_num does not fit into a u32.

pub fn input_notes_commitment(&self) -> Word

Returns the commitment to the batch’s input notes.

pub fn batch_note_tree_root(&self) -> Word

Returns the root of the batch’s note tree.

pub fn batch_expiration_block_num(&self) -> BlockNumber

Returns the block number at which the batch expires.

pub fn into_stack_outputs(self) -> StackOutputs

Encodes these BatchOutputs into the batch kernel’s output stack.

This is the inverse of BatchOutputs::parse; the resulting stack is laid out as:

[INPUT_NOTES_COMMITMENT, BATCH_NOTE_TREE_ROOT, batch_expiration_block_num]
