Struct Stats

pub struct Stats {
    pub num_records: i64,
    pub min_values: HashMap<String, ColumnValueStat>,
    pub max_values: HashMap<String, ColumnValueStat>,
    pub null_count: HashMap<String, ColumnCountStat>,
}

Statistics associated with Add actions contained in the Delta log.

Fields

num_records: i64

Number of records in the file associated with the log action.

min_values: HashMap<String, ColumnValueStat>

Contains a value smaller than all values present in the file for all columns.

max_values: HashMap<String, ColumnValueStat>

Contains a value larger than all values present in the file for all columns.

null_count: HashMap<String, ColumnCountStat>

The number of null values for all columns.

Trait Implementations

impl Debug for Stats

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

Formats the value using the given formatter.

impl Default for Stats

fn default() -> Stats

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Stats

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Stats

fn eq(&self, other: &Stats) -> 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 Stats

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Stats

impl StructuralPartialEq for Stats
