Enum Value

pub enum Value {
    Base(ScalarValue),
    List(Vec<Value>),
    Mapping(HashMap<String, Value>),
    Config(Config),
}

This represents a value in a configuration.

Variants

Base(ScalarValue)

These are the scalar values.

List(Vec<Value>)

This is a list of values.

Mapping(HashMap<String, Value>)

This is a mapping of strings to values.

Config(Config)

This is a nested (sub-) configuration.

Implementations

impl Value

pub fn as_string(&self) -> String

Expect a value to be a string and return it. Panic if it’s not the expected type.

pub fn as_i64(&self) -> i64

Expect a value to be an integer and return it. Panic if it’s not the expected type.

pub fn as_f64(&self) -> f64

Expect a value to be a floating-point value and return it. Panic if it’s not the expected type.

pub fn as_c64(&self) -> Complex64

Expect a value to be a complex number and return it. Panic if it’s not the expected type.

pub fn as_bool(&self) -> bool

Expect a value to be a Boolean and return it. Panic if it’s not the expected type.

pub fn as_date(&self) -> NaiveDate

Expect a value to be a date and return it. Panic if it’s not the expected type.

pub fn as_datetime(&self) -> DateTime<FixedOffset>

Expect a value to be a date/time and return it. Panic if it’s not the expected type.

pub fn as_list(&self) -> Vec<Value>

Expect a value to be a list and return it. Panic if it’s not the expected type.

pub fn as_mapping(&self) -> HashMap<String, Value>

Expect a value to be a mapping and return it. Panic if it’s not the expected type.

pub fn as_config(&self) -> Config

Expect a value to be a sub-configuration and return it. Panic if it’s not the expected type.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl Display for Value

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

Formats the value using the given formatter.

impl From<&str> for Value

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<Complex<f64>> for Value

fn from(value: Complex64) -> Self

Converts to this type from the input type.

impl From<DateTime<FixedOffset>> for Value

fn from(value: DateTime<FixedOffset>) -> Self

Converts to this type from the input type.

impl From<NaiveDate> for Value

fn from(value: NaiveDate) -> Self

Converts to this type from the input type.

impl From<String> for Value

impl PartialEq for Value

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