Struct iceberg::spec::Struct

pub struct Struct { /* private fields */ }

The partition struct stores the tuple of partition values for each file. Its type is derived from the partition fields of the partition spec used to write the manifest file. In v2, the partition struct’s field ids must match the ids from the partition spec.

Implementations

impl Struct

pub fn empty() -> Self

Create a empty struct.

pub fn iter(&self) -> impl ExactSizeIterator<Item = Option<&Literal>>

Create a iterator to read the field in order of field_value.

pub fn is_null_at_index(&self, index: usize) -> bool

returns true if the field at position index is null

Trait Implementations

impl Clone for Struct

fn clone(&self) -> Struct

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Struct

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

Formats the value using the given formatter.

impl FromIterator<Option<Literal>> for Struct

fn from_iter<I: IntoIterator<Item = Option<Literal>>>(iter: I) -> Self

Creates a value from an iterator.

impl Hash for Struct

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Index<usize> for Struct

type Output = Literal

The returned type after indexing.

fn index(&self, idx: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl IntoIterator for Struct

type Item = Option<Literal>

The type of the elements being iterated over.

type IntoIter = StructValueIntoIter

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for Struct

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Eq for Struct
