Struct QueryParams 

pub struct QueryParams(pub Vec<(String, ParamValue)>);

Represent parameters that can be passed to bind values during queries.

ClickHouse has very specific syntax for how it manages query parameters. Refer to their docs for more information.

Trait Implementations

impl Clone for QueryParams

fn clone(&self) -> QueryParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryParams

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

Formats the value using the given formatter.

impl Default for QueryParams

fn default() -> QueryParams

Returns the “default value” for a type.

impl From<QueryParams> for Settings

fn from(value: QueryParams) -> Settings

Helpful to serialize params when dispatching a query

impl<T, K, S> From<T> for QueryParams

where T: IntoIterator<Item = (K, S)>, K: Into<String>, ParamValue: From<S>,

fn from(value: T) -> Self

Converts to this type from the input type.

impl<K, S> FromIterator<(K, S)> for QueryParams

where K: Into<String>, ParamValue: From<S>,

fn from_iter<T>(iter: T) -> Self

where T: IntoIterator<Item = (K, S)>,

Creates a value from an iterator.

impl PartialEq for QueryParams

fn eq(&self, other: &QueryParams) -> 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.
