Enum config::Value

pub enum Value<'a> {
    String(Cow<'a, str>),
    Integer(i64),
    Float(f64),
    Boolean(bool),
    Table(HashMap<String, Value<'a>>),
    Array(Vec<Value<'a>>),
}

A configuration value.

Has an underlying or native type that comes from the configuration source but will be coerced into the requested type.

Variants

String(Cow<'a, str>)Integer(i64)Float(f64)Boolean(bool)Table(HashMap<String, Value<'a>>)Array(Vec<Value<'a>>)

Methods

impl<'a> Value<'a>

fn as_str(&'a self) -> Option<Cow<'a, str>>

Gets the underlying value as a string, performing a conversion only if neccessary.

fn as_bool(&self) -> Option<bool>

Gets the underlying type as a boolean, performing a conversion only if neccessary.

fn as_int(&self) -> Option<i64>

Gets the underlying type as an integer, performing a conversion only if neccessary.

fn as_float(&self) -> Option<f64>

Gets the underlying type as a floating-point, performing a conversion only if neccessary.
