Enum FieldMatchMode

pub enum FieldMatchMode {
    Id,
    Name,
}

Defines how Arrow fields are matched with Iceberg fields when converting data.

This enum provides two strategies for matching fields:

• Id: Match fields by their ID, which is stored in Arrow field metadata.
• Name: Match fields by their name, ignoring the field ID.

The ID matching mode is the default and preferred approach as it’s more robust against schema evolution where field names might change but IDs remain stable. The name matching mode can be useful in scenarios where field IDs are not available or when working with systems that don’t preserve field IDs.

Variants

Id

Match fields by their ID stored in Arrow field metadata

Name

Match fields by their name, ignoring field IDs

Implementations

impl FieldMatchMode

pub fn match_field( &self, arrow_field: &FieldRef, iceberg_field: &NestedField, ) -> bool
