Trait Implementations

impl Arbitrary for StartsWith

type Parameters = ()

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = fn() -> StartsWith

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_top: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for StartsWith

fn clone(&self) -> StartsWith

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StartsWith

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StartsWith

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for StartsWith

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

Formats the value using the given formatter.

impl<'a> EagerBinaryFunc<'a> for StartsWith

type Input1 = Datum<'a>

type Input2 = Datum<'a>

type Output = Datum<'a>

fn call( &self, a: Self::Input1, b: Self::Input2, temp_storage: &'a RowArena, ) -> Self::Output

fn output_type( &self, input_type_a: ColumnType, input_type_b: ColumnType, ) -> ColumnType

The output ColumnType of this function

fn introduces_nulls(&self) -> bool

Whether this function will produce NULL on non-NULL input

fn propagates_nulls(&self) -> bool

Whether this function will produce NULL on NULL input

fn could_error(&self) -> bool

Whether this function could produce an error

fn negate(&self) -> Option<BinaryFunc>

Returns the negation of the given binary function, if it exists.

fn is_monotone(&self) -> (bool, bool)

fn is_infix_op(&self) -> bool

impl Hash for StartsWith

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 MzReflect for StartsWith

fn add_to_reflected_type_info(rti: &mut ReflectedTypeInfo)

Adds names and types of the fields of the struct or enum to rti.

impl Ord for StartsWith

fn cmp(&self, other: &StartsWith) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for StartsWith

fn eq(&self, other: &StartsWith) -> 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 PartialOrd for StartsWith

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for StartsWith

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
