Implementations

impl DataStats

pub fn new() -> Self

Create new stats.

pub const fn rows(self, count: u64) -> Self

Set row count.

pub const fn columns(self, count: u32) -> Self

Set column count.

pub const fn size_bytes(self, bytes: u64) -> Self

Set size in bytes.

pub fn null_percentage(self, pct: f32) -> Self

Set null percentage.

pub fn duplicate_percentage(self, pct: f32) -> Self

Set duplicate percentage.

pub fn formatted_size(&self) -> Option<String>

Format size for display.

pub fn formatted_rows(&self) -> Option<String>

Format row count for display.

Trait Implementations

impl Clone for DataStats

fn clone(&self) -> DataStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataStats

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

Formats the value using the given formatter.

impl Default for DataStats

fn default() -> DataStats

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DataStats

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DataStats

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
