Implementations

impl ParsedQuery

A ParsedQuery represents a parsed but potentially invalid query to the query algebrizer. Such a query is syntactically valid but might be semantically invalid, for example because constraints on the set of variables are not respected.

We split ParsedQuery from FindQuery because it’s not easy to generalize over containers (here, Vec and BTreeSet) in Rust.

pub fn in_vars(&self) -> Vec<Variable>

Extract a flat list of variables from in_bindings (each binding contributes its variable(s)).

Trait Implementations

impl Clone for ParsedQuery

fn clone(&self) -> ParsedQuery

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParsedQuery

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

Formats the value using the given formatter.

impl Display for ParsedQuery

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

Formats the value using the given formatter.

impl Eq for ParsedQuery

impl FromStr for ParsedQuery

type Err = ParseError<LineCol>

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

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

impl PartialEq for ParsedQuery

fn eq(&self, other: &ParsedQuery) -> 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.
