Struct ConfigParameters

pub struct ConfigParameters { /* private fields */ }

Configuration parameters holder

Implementations

impl ConfigParameters

pub fn new(parameters: HashMap<String, String>) -> Self

Constructor

pub fn add_source( &mut self, source: &impl ConfigSource, ) -> Result<(), ConfigError>

Fill the holder with parameters from a source

pub fn get(&self, name: &str) -> Option<String>

Fetch a parameter from the holder.

pub fn get_or(&self, name: &str, default: &str) -> String

Fetch a parameter from the holder. If the parameter is not set, the given default value is returned instead.

pub fn require(&self, name: &str) -> Result<String, ConfigError>

Fetch a parameter from the holder. If the parameter is not set, an error is raised.

Trait Implementations

impl Debug for ConfigParameters

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

Formats the value using the given formatter.

impl Default for ConfigParameters

fn default() -> ConfigParameters

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ConfigParameters

where ConfigParameters: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ConfigParameters

fn eq(&self, other: &ConfigParameters) -> 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.
