Implementations

impl JoinType

pub fn is_outer(self) -> bool

Trait Implementations

impl Clone for JoinType

fn clone(&self) -> JoinType

Returns a copy 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<(), Error>

Formats the value using the given formatter.

impl Display for JoinType

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

Formats the value using the given formatter.

impl FromStr for JoinType

type Err = DataFusionError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<JoinType, DataFusionError>

Parses a string s to return a value of this type.

impl Hash for JoinType

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

where __H: Hasher,

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.
