impl ColumnCommitmentMetadataMapExt for ColumnCommitmentMetadataMap

fn from_column_fields_with_max_bounds(columns: &[ColumnField]) -> Self

Construct this mapping from a slice of column fields, with the bounds of each column set to the widest possible bounds for the column type.

fn from_columns<'a>( columns: impl IntoIterator<Item = (&'a Ident, &'a CommittableColumn<'a>)>, ) -> Self

where Self: Sized,

Construct this mapping from an iterator of column ident and columns.

fn try_union(self, other: Self) -> Result<Self, ColumnCommitmentsMismatch>

where Self: Sized,

fn try_difference(self, other: Self) -> Result<Self, ColumnCommitmentsMismatch>

where Self: Sized,
