Struct State

pub struct State<'a, T: Queryable> {
    pub data: Data<'a, T>,
    pub root: &'a T,
}

Represents the state of a query, including the current data and the root object. It is used to track the progress of a query as it traverses through the data structure.

Fields

data: Data<'a, T>

root: &'a T

Implementations

impl<'a, T: Queryable> State<'a, T>

Trait Implementations

impl<'a, T: Clone + Queryable> Clone for State<'a, T>

fn clone(&self) -> State<'a, T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, T: Debug + Queryable> Debug for State<'a, T>

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

Formats the value using the given formatter.

impl<'a, T: Queryable> Display for State<'a, T>

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

Formats the value using the given formatter.

impl<'a, T: Queryable> From<&'a T> for State<'a, T>

fn from(root: &'a T) -> Self

Converts to this type from the input type.

impl<'a, T: PartialEq + Queryable> PartialEq for State<'a, T>

fn eq(&self, other: &State<'a, T>) -> 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.
