Enum JoinType 

pub enum JoinType {
    Inner,
    Left,
    Right,
    Full,
    Semi,
    Anti,
}

Type of join to perform.

Variants

Inner

Emit only matching row pairs.

Left

Emit all left rows; unmatched left rows have NULL right columns.

Right

Emit all right rows; unmatched right rows have NULL left columns.

Full

Emit all rows from both sides; unmatched rows have NULLs.

Semi

Emit left rows that have at least one match (no right columns).

Anti

Emit left rows that have no match (no right columns).

Trait Implementations

impl Clone for JoinType

fn clone(&self) -> JoinType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JoinType

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

Formats the value using the given formatter.

impl Display for JoinType

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

Formats the value using the given formatter.

impl Hash for JoinType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for JoinType

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