Struct LogicalTable

pub struct LogicalTable {
    pub alias: String,
    pub data_transforms: Option<Vec<TransformOperation>>,
    pub source: LogicalTableSource,
}

A logical table is a unit that joins and that data transformations operate on. A logical table has a source, which can be either a physical table or result of a join. When a logical table points to a physical table, the logical table acts as a mutable copy of that physical table through transform operations.

Fields

alias: String

A display name for the logical table.

data_transforms: Option<Vec<TransformOperation>>

Transform operations that act on this logical table.

source: LogicalTableSource

Source of this logical table.

Trait Implementations

impl Clone for LogicalTable

fn clone(&self) -> LogicalTable

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LogicalTable

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

Formats the value using the given formatter.

impl Default for LogicalTable

fn default() -> LogicalTable

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LogicalTable

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LogicalTable

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
