Struct FieldSummary

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

Field summary for partition field in the spec.

Each field in the list corresponds to a field in the manifest file’s partition spec.

Fields

contains_null: bool

field: 509

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

contains_nan: Option<bool>

field: 518 Whether the manifest contains at least one partition with a NaN value for the field

lower_bound: Option<ByteBuf>

field: 510 The minimum value for the field in the manifests partitions.

upper_bound: Option<ByteBuf>

field: 511 The maximum value for the field in the manifests partitions.

Trait Implementations

impl Clone for FieldSummary

fn clone(&self) -> FieldSummary

Returns a copy 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

Formats the value using the given formatter.

impl Default for FieldSummary

fn default() -> FieldSummary

Returns the “default value” for a type.

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

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for FieldSummary

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 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::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
