Struct wick_packet::RuntimeConfig

pub struct RuntimeConfig(/* private fields */);

Implementations

impl RuntimeConfig

pub fn coerce_key<T>(&self, key: &str) -> Result<T, Error>where T: DeserializeOwned,

Get a value from the configuration map, deserializing it into the target type.

pub fn has(&self, key: &str) -> bool

Check if a value exists in the configuration map.

pub fn get(&self, key: &str) -> Option<&Value>

Get a value from the configuration map.

pub fn from_value(value: Value) -> Result<Self, Error>

Convert a serde_json::Value into a RuntimeConfig.

Trait Implementations

impl Clone for RuntimeConfig

fn clone(&self) -> RuntimeConfig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RuntimeConfig

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

Formats the value using the given formatter.

impl Default for RuntimeConfig

fn default() -> RuntimeConfig

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RuntimeConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<K, const N: usize> From<[(K, Value); N]> for RuntimeConfigwhere K: Into<String>,

fn from(arr: [(K, Value); N]) -> Self

Examples

use wick_packet::RuntimeConfig;

let config = RuntimeConfig::from([("key1", "value".into()), ("key2", 4.into())]);
let key1 = config.coerce_key::<String>("key1").unwrap();
assert_eq!(key1, "value");

let key2 = config.coerce_key::<u16>("key2").unwrap();
assert_eq!(key2, 4);

impl From<HashMap<String, Value, RandomState>> for RuntimeConfig

fn from(value: HashMap<String, Value>) -> Self

Converts to this type from the input type.

impl From<RuntimeConfig> for HashMap<String, Value>

fn from(value: RuntimeConfig) -> Self

Converts to this type from the input type.

impl IntoIterator for RuntimeConfig

type Item = (String, Value)

The type of the elements being iterated over.

type IntoIter = IntoIter<String, Value>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq<RuntimeConfig> for RuntimeConfig

fn eq(&self, other: &RuntimeConfig) -> 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 Serialize for RuntimeConfig

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

Serialize this value into the given Serde serializer.

impl TryFrom<Value> for RuntimeConfig

type Error = Error

The type returned in the event of a conversion error.

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

Performs the conversion.
