impl FromStr for AggregateFunction

type Err = DataFusionError

The associated error which can be returned from parsing.

fn from_str(name: &str) -> Result<AggregateFunction>

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

impl PartialEq<AggregateFunction> for AggregateFunction

fn eq(&self, other: &AggregateFunction) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<AggregateFunction> for AggregateFunction

fn partial_cmp(&self, other: &AggregateFunction) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool
