Values present in iceberg type

Float and Double compare as Java’s Float.compare and Double.compare do: -0.0 is less than 0.0, and every NaN is the same value, greater than all others. iceberg-java compares partition values this way, so -0.0 and 0.0 are different partitions. The spec states the same rule: floating point partition values are equal if their IEEE 754 bit layouts are equal, with NaNs normalized.

Implementations

impl PrimitiveLiteral

pub fn is_nan(&self) -> bool

Returns true if the Literal represents a primitive type that can be a NaN, and that it’s value is NaN

Trait Implementations

impl Clone for PrimitiveLiteral

fn clone(&self) -> PrimitiveLiteral

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrimitiveLiteral

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

Formats the value using the given formatter.

impl From<Datum> for PrimitiveLiteral

fn from(value: Datum) -> Self

Converts to this type from the input type.

impl Hash for PrimitiveLiteral

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 PartialEq for PrimitiveLiteral

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

impl PartialOrd for PrimitiveLiteral

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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