QueryAnalyzer

Struct QueryAnalyzer 

Source
pub struct QueryAnalyzer;
Expand description

查询分析器

自动检测查询字符串的类型并提取实际查询内容。

Implementations§

Source§

impl QueryAnalyzer

Source

pub fn analyze(query_str: &str) -> (QueryType, String)

分析查询字符串,返回查询类型和清理后的查询内容

§规则
  • * 结尾 → 前缀搜索,去除 *
  • ~ 开头 → 模糊搜索,去除 ~
  • 其他 → 标准搜索
§示例
use xore_search::query::{QueryAnalyzer, QueryType};

let (qtype, query) = QueryAnalyzer::analyze("config*");
assert_eq!(qtype, QueryType::Prefix);
assert_eq!(query, "config");

let (qtype, query) = QueryAnalyzer::analyze("~databse");
assert_eq!(qtype, QueryType::Fuzzy);
assert_eq!(query, "databse");

let (qtype, query) = QueryAnalyzer::analyze("error");
assert_eq!(qtype, QueryType::Standard);
assert_eq!(query, "error");
Source

pub fn detect_type(query_str: &str) -> QueryType

检测查询类型(不返回清理后的查询)

impl<T> Downcast for T
where T: Any,

Source§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
Source§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
Source§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
Source§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

where T: Any + Send + Sync,

Source§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
