Enum config::Value

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

A configuration value.

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

Methods

impl Value

fn into_str(self) -> Option<String>

Converts self into a string, if possible. Returns None otherwise.

fn into_bool(self) -> Option<bool>

Converts self into a bool, if possible. Returns None otherwise.

fn into_int(self) -> Option<i64>

Converts self into an i64, if possible. Returns None otherwise.

fn into_float(self) -> Option<f64>

Converts self into a f64, if possible. Returns None otherwise.

fn into_table(self) -> Option<HashMap<String, Value>>

If the Value is a Table, returns the associated Map. Returns None otherwise.

fn into_array(self) -> Option<Vec<Value>>

If the Value is an Array, returns the associated Vector. Returns None otherwise.

Trait Implementations

impl Debug for Value

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Clone for Value

fn clone(&self) -> Value
