Implementations

impl IcebergType

pub fn primitive_name(&self) -> Option<String>

The type name as it appears in Iceberg’s JSON schema representation (primitives are bare strings; struct/list/map are objects, matching how a real Iceberg schema is expressed - not shown here as JSON since field-ID assignment is the caller’s job, but the primitive name is stable and useful on its own).

pub fn from_arrow_type(dt: &DataType) -> Self

Infers the Iceberg type for an Arrow [DataType]. Nested types recurse into genuine struct/list/map shapes with placeholder field IDs (0) - see the module doc comment.

pub fn to_arrow_type(&self) -> DataType

The Arrow type this Iceberg type round-trips through.

pub fn from_pg_type(pg: &PgType) -> Self

pub fn to_pg_type(&self) -> PgType

Trait Implementations

impl Clone for IcebergType

fn clone(&self) -> IcebergType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IcebergType

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

Formats the value using the given formatter.

impl PartialEq for IcebergType

fn eq(&self, other: &IcebergType) -> 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.
