A raw Clickhouse value. Types are not strictly/completely preserved (i.e. types String and FixedString both are value String). Use this if you want dynamically typed queries.

Implementations

impl Value

pub fn string(value: impl Into<String>) -> Self

pub fn unwrap_array_ref(&self) -> &[Value]

pub fn unwrap_array(self) -> Vec<Value>

pub fn unwrap_tuple(self) -> Vec<Value>

pub fn unarray(self) -> Option<Vec<Value>>

pub fn to_value<T: FromSql>(self, type_: &Type) -> Result<T>

Converts a Value to a [T] type by calling [T::from_sql].

pub fn from_value<T: ToSql>(value: T) -> Result<Self>

Converts a [T] type to a Value by calling [T::to_sql].

pub fn guess_type(&self) -> Type

Guesses a Type from the value, may not correspond to actual column type in Clickhouse

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Value

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Value

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

Formats the value using the given formatter.

impl FromSql for Value

fn from_sql(_type_: &Type, value: Value) -> Result<Self>

impl Hash for Value

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 PartialEq for Value

fn eq(&self, other: &Self) -> 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 !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Value

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToSql for Value

fn to_sql(self, _type_hint_: Option<&Type>) -> Result<Value>

impl Eq for Value
