Struct libhaystack::haystack::val::string::Str

pub struct Str {
    pub value: String,
}

Haystack Str

Example

Create Str value

use libhaystack::val::*;

// Create `Str` from `&str` primitive
let str_value = Value::from(Str::from("sample string"));
assert!(str_value.is_str());

// Get the `Str` value from the Value
assert_eq!(Str::try_from(&str_value).unwrap(), Str::from("sample string"));
// Get a std::String from a Value
assert_eq!(String::try_from(&str_value).unwrap(), "sample string");

// Create `Str` from literal
let str:Str = "sample string".into();
assert_eq!(str.as_str(), "sample string");

Fields

value: String

Implementations

impl Str

pub fn make(val: &str) -> Self

Constructs a Str

pub fn as_str(&self) -> &str

Get a &str slice of the underlying String payload

Trait Implementations

impl Clone for Str

fn clone(&self) -> Str

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Str

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

Formats the value using the given formatter.

impl Default for Str

fn default() -> Str

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Str

Hayson Str deserializer

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

Deserialize this value from the given Serde deserializer.

impl From<&str> for Str

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<Str> for Value

Converts from Str to a Str Value

fn from(value: Str) -> Self

Converts to this type from the input type.

impl Hash for Str

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 Str

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Str

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Str

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

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

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

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

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

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

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

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

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 ToZinc for Str

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

fn to_zinc_string(&self) -> Result<String>

Encodes this Haystack type as a Zinc string

impl TryFrom<&Value> for Str

Tries to convert from Str Value to a Str

type Error = &'static str

The type returned in the event of a conversion error.

fn try_from(value: &Value) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Str
