Enum Value 

#[non_exhaustive]
pub enum Value {
    Null,
    Bool(bool),
    Int(i64),
    Number(f64),
    Str(Arc<str>),
    List(Vec<Value>),
    Map(Map),
}

A fully-resolved HCL value.

Value is what a resolved Expression reduces to. Anything that cannot resolve statically stays as Expression::Unresolved.

Equality

Value is PartialEq but not Eq or Hash because Value::Number wraps an f64 and f64::NAN != f64::NAN. Treat Value as a value type, not as a map / set key. If you need a hashable key, hash the canonical JSON form (20-parquet-exporter.md § 3.3) or wrap the number in your own total-order container.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Null

HCL null.

Bool(bool)

Boolean.

Int(i64)

Integer literal (fast path; preserved verbatim from the source).

Number(f64)

Floating-point number — the default HCL2 numeric representation.

Str(Arc<str>)

UTF-8 string (interned-friendly via Arc<str>).

List(Vec<Value>)

Heterogeneous list.

Map(Map)

Insertion-ordered map.

Implementations

impl Value

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

Returns the contained string slice, if self is a Value::Str.

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

Returns the contained boolean, if self is a Value::Bool.

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

Returns the contained integer, if self is a Value::Int.

pub fn is_null(&self) -> bool

Whether this value contains no information.

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<'de> Deserialize<'de> for Value

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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.

impl Serialize for Value

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
