Enum Value 

#[non_exhaustive]
pub enum Value {
    Bool(bool),
    Uint(u64),
    Int(i64),
    Float(f32),
    Double(f64),
    Utf8(String),

}

A decoded Matter TLV value, collapsed across wire widths.

Integer widths and float widths are erased from the public type — the encoder chooses the minimal wire width per the spec, and the decoder produces the same Rust type regardless of the width the bytes used. If you need exact-byte round-trip for non-minimal inputs, use the reader’s span APIs (crate::TlvReader::element_span / crate::TlvReader::skip_container_span + crate::TlvReader::span_bytes), which expose an element’s raw bytes for width-preserving re-emission.

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.

Bool(bool)

A boolean.

Uint(u64)

An unsigned integer, encoded on the wire in 1, 2, 4, or 8 bytes (minimal width).

Int(i64)

A signed integer, encoded on the wire in 1, 2, 4, or 8 bytes (minimal width).

Float(f32)

A 4-byte IEEE 754 single-precision float.

Double(f64)

An 8-byte IEEE 754 double-precision float.

Utf8(String)

A UTF-8 string. The wire format is a 1/2/4/8-byte little-endian length field (writer picks the minimal width) followed by the raw UTF-8 bytes. The reader rejects invalid UTF-8 with crate::Error::InvalidUtf8.

Bytes(Vec<u8>)

An octet string. The wire format is a 1/2/4/8-byte little-endian length field (writer picks the minimal width) followed by the raw bytes.

Structure(Vec<(Tag, Value)>)

A structure. Each member carries its own tag; members are typically context-tagged but the spec permits any non-anonymous form.

Array(Vec<Value>)

An array. Elements share a single type; the spec requires every element to carry an anonymous tag, which the reader enforces and the writer always emits.

List(Vec<(Tag, Value)>)

A list. Members may carry any tag form (including anonymous), and member types are not required to be uniform.

Null

The TLV null value (element type 0x14).
