/// This enum provides all the possible filter operations that can be used

/// and provide rich comparison capabilities.

/// # Example
/// ```no_run
/// use baserow_rs::{ConfigBuilder, Baserow, BaserowTableOperations, filter::Filter, api::client::BaserowClient};
/// use std::collections::HashMap;
/// use serde_json::Value;

///         .base_url("https://api.baserow.io")
///         .api_key("your-api-key")
///         .build();
///
///     let baserow = Baserow::with_configuration(config);
///     let table = baserow.table_by_id(1234);
///
///     // Query with multiple filters
///     let results = table.rows()
///         .filter_by("Status", Filter::Equal, "Active")
