Struct QueryOption 

pub struct QueryOption {
    pub key_word_like_fields: Vec<String>,
    pub select: Vec<String>,
    pub field_like: Vec<FieldCondition>,
    pub field_eq: Vec<FieldCondition>,
    pub order_by: Vec<(String, bool)>,
    pub joins: Vec<JoinOption>,
    pub where_and: Vec<String>,
    pub left_join: Vec<JoinOption>,
    pub extra_where: Vec<WhereFragment>,
}

查询选项（对齐 TS 版 QueryOp，保留核心字段）

Fields

key_word_like_fields: Vec<String>

需要模糊查询的字段

select: Vec<String>

查询字段

field_like: Vec<FieldCondition>

字段模糊查询

field_eq: Vec<FieldCondition>

字段相等查询

order_by: Vec<(String, bool)>

排序配置

joins: Vec<JoinOption>

关联配置

where_and: Vec<String>

额外的 AND 条件（字符串片段），用于快速拼接简单 where

left_join: Vec<JoinOption>

左连接配置（与 joins 等价，此处为兼容 TS 命名）

extra_where: Vec<WhereFragment>

自定义 where 片段（带参数），用于复杂过滤

Implementations

impl QueryOption

pub fn new() -> Self

pub fn key_word_like_fields<I, S>(self, fields: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

pub fn select<I, S>(self, fields: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

pub fn add_field_eq( self, column: impl Into<String>, request_param: impl Into<String>, ) -> Self

pub fn add_field_like( self, column: impl Into<String>, request_param: impl Into<String>, ) -> Self

pub fn add_order_by(self, column: impl Into<String>, asc: bool) -> Self

pub fn add_left_join( self, entity: impl Into<String>, alias: impl Into<String>, condition: impl Into<String>, join_type: JoinType, ) -> Self

pub fn add_where_and(self, cond: impl Into<String>) -> Self

pub fn add_where_raw<I, V>(self, sql: impl Into<String>, params: I) -> Self

where I: IntoIterator<Item = V>, V: Into<Value>,

pub fn add_where_with<F>(self, f: F) -> Self

where F: FnOnce(WhereBuilder) -> WhereBuilder,

通过函数式方式追加 where 片段（便捷包装）
