Struct DummyQueryProcessor 

pub struct DummyQueryProcessor {}

Dummy query processor implementation

This dummy query processor always returns the literal haystack as a single non-matching Part. This can be useful when you want to apply a function that expects a query processor, without actually applying the query.

Implementations

impl DummyQueryProcessor

pub fn create() -> DshApiResult<Self>

Trait Implementations

impl Clone for DummyQueryProcessor

fn clone(&self) -> DummyQueryProcessor

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DummyQueryProcessor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for DummyQueryProcessor

fn eq(&self, other: &DummyQueryProcessor) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl QueryProcessor for DummyQueryProcessor

fn describe(&self) -> String

Returns a description of the query

fn matching(&self, haystack: &str) -> Option<Match>

Applies generic query to string

fn matching_expression( &self, _haystack: &str, ) -> Option<(String, String, Option<String>)>

Applies expression query to string

fn matching_parts(&self, haystack: &str) -> Option<Vec<Part>>

Applies parts query to string

fn matching_simple(&self, _haystack: &str) -> bool

Applies simple query to string
