Implementations

impl Series

pub fn name(&self) -> &str

pub fn key_column_type(&self) -> Option<Type>

Returns the Type of the key column, if the key column is found in columns.

pub fn key_to_u64(&self, value: Value) -> Option<u64>

Convert a Value to u64 for series key encoding.

Handles both integer and datetime key types. For datetime keys, the nanos-since-epoch value is divided by the precision factor to recover the original u64 key. Negative values (pre-1970 dates, negative integers) are rejected.

pub fn key_from_u64(&self, v: u64) -> Value

Convert a u64 key value back to the appropriate Value type for encoding.

pub fn key_column_data(&self, keys: Vec<u64>) -> ColumnData

Build a ColumnData from u64 key values using the proper key column type.

pub fn data_columns(&self) -> impl Iterator<Item = &Column>

Returns columns excluding the key column (data columns only).

Trait Implementations

impl Clone for Series

fn clone(&self) -> Series

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Series

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Series

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Series

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
