Enum Value 

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

A single Thing property value — closed sum, JSON-shaped.

Value deliberately does not provide arithmetic or comparison helpers; protocol crates lift it into typed shapes via DataType (see the crate::binding module).

Variants

Null

Explicit null. Encoded as JSON null.

Bool(bool)

true / false.

Int(i64)

Integer in the i64 range. Most industrial sensors fit here.

Float(f64)

IEEE-754 double. Use when the source has fractional units.

Str(SmolStr)

Short string — backed by SmolStr so values up to 23 bytes are inline.

Array(Vec<Value>)

Heterogeneous list. Requires the alloc feature (always enabled by default; only MCU-with-no-allocator builds turn it off).

Object(BTreeMap<String, Value>)

Object with string keys. Requires the alloc feature.

Implementations

impl Value

pub const fn is_null(&self) -> bool

Returns true if the value is Value::Null.

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

Borrow the inner string if self is Value::Str.

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

Returns the inner integer if self is Value::Int.

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

Returns the inner float if self is Value::Float or Value::Int (lossy widening on Int).

Trait Implementations
