Struct tomsg_rs::Id

pub struct Id(_);

An Id is a non-negative 64-bit integer.

You can obtain an Id by calling try_from with a i64 argument:

use tomsg_rs::Id;
use std::convert::TryFrom;

let valid: i64 = 0;
let invalid: i64 = -1;

assert!(Id::try_from(valid).is_ok());
assert!(Id::try_from(invalid).is_err());

Implementations

impl Id

#[must_use]

pub const unsafe fn from_i64_unchecked(val: i64) -> Self

Create an Id from the given val.

Safety

This function is unsafe because the val is not checked on conformity, only use this function if you’re sure that the given val is non-negative.

Trait Implementations

impl Clone for Id

fn clone(&self) -> Id

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Id

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

Formats the value using the given formatter.

impl Default for Id

fn default() -> Id

Returns the “default value” for a type.

impl Display for Id

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

Formats the value using the given formatter.

impl Hash for Id

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl Ord for Id

fn cmp(&self, other: &Id) -> Ordering

This method returns an Ordering between self and other.

#[must_use]

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]

fn clamp(self, min: Self, max: Self) -> Self

impl PartialEq<Id> for Id

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<Id> for Id

fn partial_cmp(&self, other: &Id) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]

This method tests less than (for self and other) and is used by the < operator.

#[must_use]

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]

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

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<i64> for Id

type Error = &'static str
