Struct Props 

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

An ordered list of props: key and value pairs.

Build it with the props! macro, with Props::with, or collect it from an iterator of pairs. Setting a key that is already there replaces its value and keeps its place.

use privatus_analytics::{props, Props};

let a = props! { "plan" => "pro", "seats" => 5, "beta" => true };
let b = Props::new().with("plan", "pro").with("seats", 5).with("beta", true);
assert_eq!(a, b);

Implementations

impl Props

pub fn new() -> Self

No props.

pub fn with(self, key: impl Into<String>, value: impl Into<Value>) -> Self

Sets a prop and returns the props, for chaining.

pub fn insert(&mut self, key: impl Into<String>, value: impl Into<Value>)

Sets a prop. A key that is already there gets the new value.

pub fn get(&self, key: &str) -> Option<&Value>

The value for a key, if there is one.

pub fn len(&self) -> usize

The number of props.

pub fn is_empty(&self) -> bool

Whether there are no props.

pub fn iter(&self) -> impl Iterator<Item = (&str, &Value)>

The props in order.

Trait Implementations

impl Clone for Props

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 Props

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

Formats the value using the given formatter.

impl Default for Props

fn default() -> Self

Returns the “default value” for a type.

impl<K: Into<String>, V: Into<Value>> Extend<(K, V)> for Props

fn extend<I: IntoIterator<Item = (K, V)>>(&mut self, iter: I)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: T)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl<K: Into<String>, V: Into<Value>> FromIterator<(K, V)> for Props

fn from_iter<I: IntoIterator<Item = (K, V)>>(iter: I) -> Self

Creates a value from an iterator.

impl IntoIterator for Props

type Item = (String, Value)

The type of the elements being iterated over.

type IntoIter = IntoIter<(String, Value)>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'a> IntoIterator for &'a Props

type Item = (&'a String, &'a Value)

The type of the elements being iterated over.

type IntoIter = Map<Iter<'a, (String, Value)>, fn(&'a (String, Value)) -> (&'a String, &'a Value)>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for Props

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

Equality operator ==.

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

Inequality operator !=.
