Struct EnvelopeProbe 

pub struct EnvelopeProbe {
    pub kind: String,
    pub format_version: u32,
}

Identifying prefix of a durable envelope document.

Readers decode this probe before the full document so that objects written with an unknown kind or an unsupported format version fail with a precise error instead of a generic decode error. kind is deliberately a string (not an enum) so future kinds remain reportable.

Fields

kind: String

Durable family declared by the stored object.

format_version: u32

Family-independent version gate declared by the stored object.
