Struct ClientOpts 

pub struct ClientOpts {
    pub client_version_major: u64,
    pub client_version_minor: u64,
    pub client_version_patch: u64,
    pub compression: Compression,
    pub read_buffer_bytes: usize,
    /* private fields */
}

Client settings sent during Hello handshake.

String values are copied and null-terminated during connection. Interior null bytes return ErrorKind::Usage.

Fields

client_version_major: u64

Client version reported in system.query_log. Default is 0.0.0.

client_version_minor: u64

client_version_patch: u64

compression: Compression

read_buffer_bytes: usize

Read buffer size in bytes. Zero selects clickhouse-c 8 KiB default.

Implementations

impl ClientOpts

pub fn new() -> Self

Creates settings for default user and database, empty password, and no compression.

pub fn client_name(self, s: &str) -> Self

Sets client name. Default is "clickhouse-c".

pub fn database(self, s: &str) -> Self

Sets default database for unqualified table names.

pub fn user(self, s: &str) -> Self

Sets account name used for authentication.

pub fn password(self, s: &str) -> Self

Sets authentication password.

Native protocol sends password as clear text inside Hello message. Use TLS when transport is not trusted.

pub fn client_version(self, major: u64, minor: u64, patch: u64) -> Self

Sets reported client version.

pub fn compression(self, compression: Compression) -> Self

Sets compression algorithm.

Compressed connections require a matching Codec in Client::init.

Trait Implementations

impl Clone for ClientOpts

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClientOpts

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

Formats the value using the given formatter.

impl Default for ClientOpts

fn default() -> Self

Returns the “default value” for a type.
