Struct KeyValue

pub struct KeyValue {
    pub key: Option<String>,
    pub value: Option<String>,
}

---

user defined key value pairs to add custom metadata to arrow key namespacing is the responsibility of the user

Generated from these locations:

• Table KeyValue in the file Schema.fbs:475

Fields

key: Option<String>

The field key in the table KeyValue

value: Option<String>

The field value in the table KeyValue

Implementations

impl KeyValue

pub fn builder() -> KeyValueBuilder<()>

Creates a KeyValueBuilder for serializing an instance of this table.

pub fn create( builder: &mut Builder, field_key: impl WriteAsOptional<Offset<str>>, field_value: impl WriteAsOptional<Offset<str>>, ) -> Offset<Self>

Trait Implementations

impl Clone for KeyValue

fn clone(&self) -> KeyValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for KeyValue

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

Formats the value using the given formatter.

impl Default for KeyValue

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for KeyValue

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for KeyValue

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 Ord for KeyValue

fn cmp(&self, other: &KeyValue) -> 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 KeyValue

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

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'a> TryFrom<KeyValueRef<'a>> for KeyValue

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: KeyValueRef<'a>) -> Result<Self>

Performs the conversion.

impl Eq for KeyValue

impl StructuralPartialEq for KeyValue

impl VectorWrite<Offset<KeyValue>> for KeyValue

Safety

The planus compiler generates implementations that initialize the bytes in write_values.

impl WriteAs<Offset<KeyValue>> for KeyValue

impl WriteAsOffset<KeyValue> for KeyValue

impl<T0: WriteAsOptional<Offset<str>>, T1: WriteAsOptional<Offset<str>>> WriteAsOffset<KeyValue> for KeyValueBuilder<(T0, T1)>

impl WriteAsOptional<Offset<KeyValue>> for KeyValue
