Struct FieldSummary

pub struct FieldSummary {
    pub contains_null: bool,
    pub contains_nan: Option<bool>,
    pub lower_bound: Option<Value>,
    pub upper_bound: Option<Value>,
}

DataFile found in Manifest.

Fields

contains_null: bool

Whether the manifest contains at least one partition with a null value for the field

contains_nan: Option<bool>

Whether the manifest contains at least one partition with a NaN value for the field

lower_bound: Option<Value>

Lower bound for the non-null, non-NaN values in the partition field, or null if all values are null or NaN. If -0.0 is a value of the partition field, the lower_bound must not be +0.0

upper_bound: Option<Value>

Upper bound for the non-null, non-NaN values in the partition field, or null if all values are null or NaN . If +0.0 is a value of the partition field, the upper_bound must not be -0.0.

Trait Implementations

impl Clone for FieldSummary

fn clone(&self) -> FieldSummary

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldSummary

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FieldSummary

fn deserialize<__D>( __deserializer: __D, ) -> Result<FieldSummary, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FieldSummary

fn eq(&self, other: &FieldSummary) -> 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 Serialize for FieldSummary

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.
