Struct JoinEdge 

pub struct JoinEdge {
    pub left_table: String,
    pub left_column: String,
    pub right_table: String,
    pub right_column: String,
    pub join_type: JoinType,
}

Information about an equijoin between two tables

Fields

left_table: String

Table name on left side of equijoin

left_column: String

Column from left table

right_table: String

Table name on right side of equijoin

right_column: String

Column from right table

join_type: JoinType

Join type (INNER, SEMI, ANTI, etc.)

Implementations

impl JoinEdge

pub fn involves_table(&self, table: &str) -> bool

Check if this edge involves a specific table

pub fn other_table(&self, table: &str) -> Option<String>

Get the other table in this edge (if input is one side)

Trait Implementations

impl Clone for JoinEdge

fn clone(&self) -> JoinEdge

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JoinEdge

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

Formats the value using the given formatter.

impl PartialEq for JoinEdge

fn eq(&self, other: &JoinEdge) -> 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.
