Unwrap into a wql::Query

Trait Implementations

impl Clone for TagFilter

fn clone(&self) -> TagFilter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TagFilter

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

Formats the value using the given formatter.

impl From<AbstractQuery<String, String>> for TagFilter

fn from(query: AbstractQuery<String, String>) -> TagFilter

Converts to this type from the input type.

impl FromStr for TagFilter

type Err = Error

The associated error which can be returned from parsing.

fn from_str(query: &str) -> Result<TagFilter, Error>

Parses a string s to return a value of this type.

impl PartialEq for TagFilter

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

This method tests for self and other values to be equal, and is used by ==.

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

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