Enum Arg 

pub enum Arg<'a> {
    ConfigFilePath(Cow<'a, str>),
    LogLevel(LogLevel),
    OutputFormat(OutputFormat),
    MultiQuery,
    Custom(Cow<'a, str>, Option<Cow<'a, str>>),
}

Query arguments that can be passed when executing queries.

Arg represents various command-line arguments that can be used to configure query execution. Most commonly, you’ll use OutputFormat to specify the desired output format.

Examples

use chdb_rust::arg::Arg;
use chdb_rust::format::OutputFormat;
use chdb_rust::log_level::LogLevel;

// Specify output format
let args = &[Arg::OutputFormat(OutputFormat::JSONEachRow)];

// Specify log level
let args = &[Arg::LogLevel(LogLevel::Debug)];

// Use custom arguments
let args = &[Arg::Custom("path".into(), Some("/tmp/db".into()))];

Variants

ConfigFilePath(Cow<'a, str>)

--config-file=<value>

LogLevel(LogLevel)

--log-level=<value>

OutputFormat(OutputFormat)

--output-format=<value>

MultiQuery

–multiquery

Custom(Cow<'a, str>, Option<Cow<'a, str>>)

Custom argument.

“–path=/tmp/chdb” translates into one of the following:

1. Arg::Custom(“path”.to_string().into(), Some(“/tmp/chdb”.to_string().into())).
2. Arg::Custom(“path”.into(), Some(“/tmp/chdb”.into())).

“–multiline” translates into one of the following:

1. Arg::Custom(“multiline”.to_string().into(), None).
2. Arg::Custom(“multiline”.into(), None).

We should tell user where to look for officially supported arguments. Here is some hint for now: https://github.com/fixcik/chdb-rs/blob/master/OPTIONS.md.
