Trait Implementations

impl Arbitrary for ByteLengthString

type Parameters = ()

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

type Strategy = fn() -> ByteLengthString

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 ByteLengthString

fn clone(&self) -> ByteLengthString

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ByteLengthString

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ByteLengthString

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ByteLengthString

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

Formats the value using the given formatter.

impl<'a> EagerUnaryFunc<'a> for ByteLengthString

type Input = &'a str

type Output = Result<i32, EvalError>

fn call(&self, a: Self::Input) -> Self::Output

fn output_type(&self, input_type: ColumnType) -> ColumnType

The output ColumnType of this function

fn preserves_uniqueness(&self) -> bool

Whether this function preserves uniqueness

fn inverse(&self) -> Option<UnaryFunc>

fn is_monotone(&self) -> bool

fn propagates_nulls(&self) -> bool

Whether this function will produce NULL on NULL input

fn introduces_nulls(&self) -> bool

Whether this function will produce NULL on non-NULL input

fn could_error(&self) -> bool

Whether this function could produce an error

impl From<ByteLengthString> for UnaryFunc

fn from(variant: ByteLengthString) -> Self

Converts to this type from the input type.

impl Hash for ByteLengthString

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 ByteLengthString

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 ByteLengthString

fn cmp(&self, other: &ByteLengthString) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ByteLengthString

fn eq(&self, other: &ByteLengthString) -> 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 ByteLengthString

fn partial_cmp(&self, other: &ByteLengthString) -> 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 ByteLengthString

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
