Lucene查询构建器Derive

用于为Rust结构体生成Lucene查询构建器的procmacro derive crate

使用方法

use lucene_query_builder::QueryBuilder;

#[derive(QueryBuilder)]
struct Person {
    name: String,
    age: i32,
}

简单查询

let query = Person::query_builder()
    .name("Bob")
    .or()
    .name("Alice")
    .build();

assert_eq!(query, "query=name:Bob OR name:Alice".to_string());

嵌套查询

let query = Person::query_builder()
    .expr(Person::query_builder().name("Bob").or().name("Alice"))
    .and()
    .age("22")
    .build();

assert_eq!(
    query,
    "query=(name:Bob OR name:Alice) AND age:22".to_string()
);

范围查询

let query = Person::query_builder().age_range("7", "77").build();

assert_eq!(query, "query=age:[7 TO 77]".to_string());

重命名构建函数和字段名称

如果您需要重命名生成的方法，可以使用#[query_builder_rename = "名称"]

#[derive(QueryBuilder)]
struct Person {
    name: String,
    age: i32,
    #[query_builder_rename = "fullname"]
    complete_name: String,
}

let query = Person::query_builder()
    .name("Bob")
    .and()
    .fullname("Bob Marley")
    .build();

assert_eq!(
    query,
    "query=name:Bob AND complete_name:\"Bob Marley\"".to_string()
);

如果您需要重命名生成的Lucene字段，可以使用#[query_builder_field = "名称"].

#[derive(QueryBuilder)]
struct Person {
    name: String,
    age: i32,
    #[query_builder_rename = "fullname"]
    #[query_builder_field = "fullname"]
    complete_name: String,
}

let query = Person::query_builder()
    .name("Bob")
    .and()
    .fullname("Bob Marley")
    .build();

assert_eq!(
    query,
    "query=name:Bob AND fullname:\"Bob Marley\"".to_string()
);

忽略字段

如果您需要忽略一个字段，请使用属性宏： #[query_builder_ignore]
