Struct IcebergSchema 

#[non_exhaustive]
pub struct IcebergSchema {
    pub schema_id: i32,
    pub identifier_field_ids: Option<Vec<i32>>,
    pub type: Option<IcebergStructTypeEnum>,
    pub fields: Vec<IcebergStructField>,
}

Defines the schema structure for an Iceberg table, including field definitions, data types, and schema metadata.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

schema_id: i32

The unique identifier for this schema version within the Iceberg table's schema evolution history.

identifier_field_ids: Option<Vec<i32>>

The list of field identifiers that uniquely identify records in the table, used for row-level operations and deduplication.

type: Option<IcebergStructTypeEnum>

The root type of the schema structure, typically "struct" for Iceberg table schemas.

fields: Vec<IcebergStructField>

The list of field definitions that make up the table schema, including field names, types, and metadata.

Implementations

impl IcebergSchema

pub fn schema_id(&self) -> i32

The unique identifier for this schema version within the Iceberg table's schema evolution history.

pub fn identifier_field_ids(&self) -> &[i32]

The list of field identifiers that uniquely identify records in the table, used for row-level operations and deduplication.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .identifier_field_ids.is_none().

pub fn type(&self) -> Option<&IcebergStructTypeEnum>

The root type of the schema structure, typically "struct" for Iceberg table schemas.

pub fn fields(&self) -> &[IcebergStructField]

The list of field definitions that make up the table schema, including field names, types, and metadata.

impl IcebergSchema

pub fn builder() -> IcebergSchemaBuilder

Creates a new builder-style object to manufacture IcebergSchema.

Trait Implementations

impl Clone for IcebergSchema

fn clone(&self) -> IcebergSchema

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IcebergSchema

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for IcebergSchema

fn eq(&self, other: &IcebergSchema) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
