pub enum Value {
    Null,
    Bool(bool),
    Int(i64),
    Float(f64),
    Str(String),
    List(Vec<Value>),
}

A resolved, typed value.

Variants

Null

No value was supplied.

Bool(bool)

Boolean flag or bool-rule value.

Int(i64)

Signed integer produced by int or port validation.

Float(f64)

Floating-point value.

Str(String)

String value.

List(Vec<Value>)

Values of an array option or variadic argument.

Implementations

impl Value

pub fn as_str(&self) -> Option<&str>

Return the string, or None for another variant.

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

Return the integer, or None for another variant.

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

Return a float, converting Int values; None for nonnumeric variants.

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

Return the boolean, or None for another variant.

pub fn as_list(&self) -> &[Value]

Return list elements, or an empty slice for another variant.

pub fn is_null(&self) -> bool

Whether this is an unset value.
