Struct Ref 

pub struct Ref {
    pub value: String,
    pub dis: Option<String>,
}

Haystack Ref

Example

Create Ref value

use libhaystack::val::*;

// Create ref from `&str` primitive
let ref_value = Value::from(Ref::from("exampleRef"));
assert!(ref_value.is_ref());
// Ref with display
let ref_dis_value = Value::from(Ref{ value: String::from("myRef"), dis: Some(String::from("sample ref")) });
assert_eq!(Ref::try_from(&ref_dis_value).unwrap().dis, Some(String::from("sample ref")));

Fields

value: String

dis: Option<String>

Implementations

impl Ref

pub fn make(val: &str, dis: Option<&str>) -> Self

Make a Ref

pub fn gen() -> Ref

Generate a new Ref based on a V4 UUID

Trait Implementations

impl Clone for Ref

fn clone(&self) -> Ref

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ref

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

Formats the value using the given formatter.

impl Default for Ref

fn default() -> Ref

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Ref

Hayson Ref deserializer

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Ref, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for Ref

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

Formats the value using the given formatter.

impl From<&str> for Ref

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<Ref> for Value

Converts from Ref to a Ref Value

fn from(value: Ref) -> Self

Converts to this type from the input type.

impl Hash for Ref

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Ref

Implement ordering used in sorting for Ref

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

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

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Ref

Implement equality operator for Ref

fn eq(&self, other: &Self) -> 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 PartialOrd for Ref

Implement partial ordering used in sorting for Ref

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for Ref

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl ToBrio for Ref

fn to_brio<W: Write>(&self, writer: &mut W) -> Result<()>
