Enum Value 

pub enum Value {
    Bool(bool),
    Float(f64),
    FloatGroup(Vec<f64>),
    String(String),
    Expression(String),
}

Liberty value type

A wide range of types are defined for the Liberty syntax. Because there is little to no way to parse enumerated types from the syntax alone, enumerated types are parsed as the Value::Expression variant.

Variants

Bool(bool)

Boolean value, parsed from the keywords true and false

Float(f64)

Floating point value.

All numbers are parsed into f64. While the Liberty specification differentiates between integers and floating point values on a per-field basis, all are parsed into an f64.

FloatGroup(Vec<f64>)

Group of floating point values in quotation marks

For example, this complex attribute

values ( \
  "1.0, 2.0, 3.0", \
  "4.0, 5.0, 6.0" \
);

will be parsed into a Vec<Value::FloatGroup>.

String(String)

String enclosed in quotation marks

Expression(String)

Expression

Enumerated values, such as the delay_model simple attribute, are parsed as a Value::Expression.

Implementations

impl Value

pub fn to_string(&self) -> String

Get a String representation of a Value

pub fn float(&self) -> f64

Convert Value::Float to f64 or panic

pub fn string(&self) -> String

Convert Value::String to String or panic

pub fn expr(&self) -> String

Convert Value::Expression to String or panic

pub fn bool(&self) -> bool

Convert Value::Bool to bool or panic

pub fn float_group(&self) -> Vec<f64>

Convert Value::FloatGroup to Vec<f64> or panic

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl PartialEq for Value

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