Struct Counter 

pub struct Counter {
    pub name: String,
    pub value: i64,
    pub increment: i64,
}

A counter-based sequence for MongoDB.

Fields

name: String

Counter/sequence name.

value: i64

Current value.

increment: i64

Increment amount.

Implementations

impl Counter

pub fn new(name: impl Into<String>) -> Self

Create a new counter.

pub fn with_increment(self, increment: i64) -> Self

Set the increment value.

pub fn with_initial_value(self, value: i64) -> Self

Set the initial value.

Trait Implementations

impl Clone for Counter

fn clone(&self) -> Counter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Counter

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Counter

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Counter

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

impl Serialize for Counter

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
