Extension trait intended for ColumnCommitmentMetadataMap.

Required Methods

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,

Combine two metadata maps as if the source table commitments are being unioned.

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

where Self: Sized,

Combine two metadata maps as if the source table commitments are being differenced.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
