Struct Predicates

pub struct Predicates(/* private fields */);

Collection of boolean predicates.

Implementations

impl Predicates

pub fn new() -> Predicates

Create empty collection.

pub fn from<S: Display + 'static>(predicate: S) -> Predicates

Creates collection containing given predicate.

pub fn from_all<S, I, IT>(predicates: I) -> Self

where S: Display + 'static, I: IntoIterator<Item = S, IntoIter = IT>, IT: Iterator<Item = S>,

Crates collection containing given predicates.

pub fn as_where<'s>(&'s self) -> PredicateStatement<'s>

Gets WHERE statement with predicates.

pub fn and_push<S: Display + 'static>(&mut self, predicate: S)

Appends predicate.

pub fn and_extend<S, I, IT>(&mut self, predicates: I)

where S: Display + 'static, I: IntoIterator<Item = S, IntoIter = IT>, IT: Iterator<Item = S>,

Appends all predicates.

pub fn and<S: Display + 'static>(self, predicate: S) -> Self

Appends predicate with fluid API.

pub fn and_all<S, I, IT>(self, predicates: I) -> Self

where S: Display + 'static, I: IntoIterator<Item = S, IntoIter = IT>, IT: Iterator<Item = S>,

Appends all predicates with fluid API.

Trait Implementations

impl IntoIterator for Predicates

type Item = Box<dyn Display>

The type of the elements being iterated over.

type IntoIter = IntoIter<Box<dyn Display>>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
