Struct PreparedQuestions 

pub struct PreparedQuestions { /* private fields */ }

A validated question set, serialized once.

Cloning it copies a reference count, not the bytes, and it can be shared between threads and reused by any number of calls.

Implementations

impl PreparedQuestions

pub fn len(&self) -> usize

The number of questions in the set. It is never zero.

pub fn is_empty(&self) -> bool

Always false: an empty set is rejected by Questions::prepare.

pub fn names( &self, ) -> impl ExactSizeIterator<Item = &str> + DoubleEndedIterator + '_

The question names, in the order they are sent.

Trait Implementations

impl Clone for PreparedQuestions

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PreparedQuestions

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

Prints the JSON the set is sent as: questions are not secrets, and the wire form is the one thing worth seeing.

impl Eq for PreparedQuestions

impl PartialEq for PreparedQuestions

Two sets are equal when their bytes are, however each was made; the sizing hint is not part of the set.

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

Equality operator ==.

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

Inequality operator !=.
