Struct Query 

pub struct Query { /* private fields */ }

Represents a database query within the rincon driver.

This struct holds the AQL query string and the query parameters needed to call the ArangoDB server to execute the database query.

Implementations

impl Query

pub fn new<Q>(query_string: Q) -> Self

where Q: Into<String>,

Constructs a new Query with the given query string.

pub fn unwrap(self) -> (String, HashMap<String, Value>)

Moves the fields out of the Query struct to reuse their values without cloning them.

After calling this function this Query instance is invalid.

pub fn str(&self) -> &str

Returns the query string as a &str.

pub fn set_parameter<N, T>(&mut self, name: N, value: T)

where N: Into<String>, T: Into<Value>,

Sets the value of a named parameter.

pub fn parameter<T>(&self, name: &str) -> Option<&T>

where T: UnwrapValue,

Returns the value of a named parameter.

Trait Implementations

impl Clone for Query

fn clone(&self) -> Query

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Query

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

Formats the value using the given formatter.

impl Display for Query

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

Formats the value using the given formatter.

impl PartialEq for Query

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