Struct Extension 

#[non_exhaustive]
pub struct Extension {
    pub arrow: Option<ArrowOptions>,
    pub chunked_send: ChunkedProtocolMode,
    pub chunked_recv: ChunkedProtocolMode,
    pub fast_mode_size: Option<u8>,
}

Extra configuration options for ClickHouse.

These options are separated to allow extending the configuration capabilities of a connection without breaking the core ClientOptions that are unlikely to ever change. For this reason, Extensions is non_exhaustive so the api can change without breaking existing implementations.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

arrow: Option<ArrowOptions>

Options specific to (de)serializing arrow data.

chunked_send: ChunkedProtocolMode

Options related to server/client protocol send chunking. This may be removed, as it may be defaulted.

chunked_recv: ChunkedProtocolMode

Options related to server/client protocol recv chunking. This may be removed, as it may be defaulted

fast_mode_size: Option<u8>

Related to inner_pool, how many ‘inner clients’ to spawn. Currently capped at 4.

Implementations

impl Extension

Configuration extensions for specialized ClickHouse client behavior.

This type provides additional configuration options beyond the standard client settings, including Arrow format options and cloud-specific settings.

pub fn with_arrow(self, options: ArrowOptions) -> Self

pub fn with_set_arrow(self, f: impl Fn(ArrowOptions) -> ArrowOptions) -> Self

pub fn with_chunked_send_mode(self, mode: ChunkedProtocolMode) -> Self

pub fn with_chunked_recv_mode(self, mode: ChunkedProtocolMode) -> Self

pub fn with_fast_mode_size(self, size: u8) -> Self

Trait Implementations

impl Clone for Extension

fn clone(&self) -> Extension

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Extension

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

Formats the value using the given formatter.

impl Default for Extension

fn default() -> Extension

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Extension

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Extension

fn eq(&self, other: &Extension) -> 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 Serialize for Extension

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
