Struct iceberg_rust::spec::values::Struct

pub struct Struct {
    pub fields: Vec<Option<Value>>,
    pub lookup: BTreeMap<String, usize>,
}

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.

Fields

fields: Vec<Option<Value>>

Vector to store the field values

lookup: BTreeMap<String, usize>

A lookup that matches the field name to the entry in the vector

Implementations

impl Struct

pub fn get(&self, name: &str) -> Option<&Option<Value>>

Get reference to partition value

pub fn get_mut(&mut self, name: &str) -> Option<&mut Option<Value>>

Get mutable reference to partition value

pub fn iter(&self) -> Iter<'_, Option<Value>>

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<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Struct

fn deserialize<D>( deserializer: D ) -> Result<Struct, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromIterator<(String, Option<Value>)> for Struct

fn from_iter<I>(iter: I) -> Struct

where I: IntoIterator<Item = (String, Option<Value>)>,

Creates a value from an iterator.

impl Hash for Struct

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

where __H: Hasher,

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 Ord for Struct

fn cmp(&self, other: &Struct) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

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 PartialOrd for Struct

fn partial_cmp(&self, other: &Struct) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Struct

fn serialize<S>( &self, serializer: S ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Struct
