impl<C: Commitment> TableCommitment<C>

pub fn from_accessor_with_max_bounds( table_ref: TableRef, columns: &[ColumnField], accessor: &impl CommitmentAccessor<C>, ) -> Self

Create a new TableCommitment for a table from a commitment accessor.

pub fn try_new( column_commitments: ColumnCommitments<C>, range: Range<usize>, ) -> Result<Self, NegativeRange>

Construct a new TableCommitment.

Will error if the range is “negative”, i.e. if its end < start.

pub fn column_commitments(&self) -> &ColumnCommitments<C>

Returns a reference to this type’s internal ColumnCommitments.

pub fn range(&self) -> &Range<usize>

Returns a reference to the range of rows this type commits to.

pub fn num_columns(&self) -> usize

Returns the number of columns in the committed table.

pub fn num_rows(&self) -> usize

Returns the number of rows that have been committed to.

pub fn try_from_columns_with_offset<'a, COL>( columns: impl IntoIterator<Item = (&'a Identifier, COL)>, offset: usize, setup: &C::PublicSetup<'_>, ) -> Result<TableCommitment<C>, TableCommitmentFromColumnsError>
where COL: Into<CommittableColumn<'a>>,

Returns a TableCommitment to the provided columns with the given row offset.

Provided columns must have the same length and no duplicate identifiers.

pub fn from_owned_table_with_offset<S>( owned_table: &OwnedTable<S>, offset: usize, setup: &C::PublicSetup<'_>, ) -> TableCommitment<C>
where S: Scalar,

Returns a TableCommitment to the provided table with the given row offset.

pub fn try_append_rows<'a, COL>( &mut self, columns: impl IntoIterator<Item = (&'a Identifier, COL)>, setup: &C::PublicSetup<'_>, ) -> Result<(), AppendTableCommitmentError>
where COL: Into<CommittableColumn<'a>>,

Append rows of data from the provided columns to the existing TableCommitment.

The row offset is assumed to be the end of the TableCommitment’s current range.

Will error on a variety of mismatches, or if the provided columns have mixed length.

pub fn append_owned_table<S>( &mut self, owned_table: &OwnedTable<S>, setup: &C::PublicSetup<'_>, ) -> Result<(), ColumnCommitmentsMismatch>
where S: Scalar,

Append data of the provided table to the exiting TableCommitment.

Will error on a variety of mismatches. See ColumnCommitmentsMismatch for an enumeration of these errors.

pub fn try_extend_columns<'a, COL>( &mut self, columns: impl IntoIterator<Item = (&'a Identifier, COL)>, setup: &C::PublicSetup<'_>, ) -> Result<(), TableCommitmentFromColumnsError>
where COL: Into<CommittableColumn<'a>>,

Add new columns to this TableCommitment.

Columns must have the same length as the current commitment and no duplicate identifiers.

pub fn try_add( self, other: Self, ) -> Result<Self, TableCommitmentArithmeticError>
where Self: Sized,

Add two TableCommitments together.

self must end where other begins, or vice versa. Otherwise, TableCommitmentArithmeticError::NonContiguous is returned.

This will also error on a variety of mismatches. See ColumnCommitmentsMismatch for an enumeration of these errors.

pub fn try_sub( self, other: Self, ) -> Result<Self, TableCommitmentArithmeticError>
where Self: Sized,

Subtract two TableCommitments.

self and other must begin at the same row number or end at the same row number. Otherwise, TableCommitmentArithmeticError::NonContiguous is returned.

Furthermore, other’s range must be smaller or equal to self’s. Otherwise, TableCommitmentArithmeticError::NegativeRange is returned.

This will also error on a variety of mismatches. See ColumnCommitmentsMismatch for an enumeration of these errors.

pub fn try_append_record_batch( &mut self, batch: &RecordBatch, setup: &C::PublicSetup<'_>, ) -> Result<(), AppendRecordBatchTableCommitmentError>

Append an arrow RecordBatch to the existing TableCommitment.

The row offset is assumed to be the end of the TableCommitment’s current range.

Will error on a variety of mismatches, or if the provided columns have mixed length.

pub fn try_from_record_batch( batch: &RecordBatch, setup: &C::PublicSetup<'_>, ) -> Result<TableCommitment<C>, RecordBatchToColumnsError>

Returns a TableCommitment to the provided arrow RecordBatch.

pub fn try_from_record_batch_with_offset( batch: &RecordBatch, offset: usize, setup: &C::PublicSetup<'_>, ) -> Result<TableCommitment<C>, RecordBatchToColumnsError>

Returns a TableCommitment to the provided arrow RecordBatch with the given row offset.
