Enum HeaderSpec 

pub enum HeaderSpec {
    Structured {
        fields: Vec<HeaderField>,
    },
    RawPrefix {
        prefix_hex: String,
        randomize_indices: Vec<usize>,
    },
}

Header Specification for dynamic per-packet header generation

Instead of storing fixed header bytes, HeaderSpec declares how to generate headers dynamically. This solves Issue #30 (WireGuard detection) by ensuring each packet has a unique but protocol-valid header.

Variants

Structured

Structured header semantics expressed as typed fields.

Fields

fields: Vec<HeaderField>

RawPrefix

Raw prefix with per-packet randomization Uses fixed bytes with optional random positions

Fields

prefix_hex: String

Fixed prefix bytes (hex string)

randomize_indices: Vec<usize>

Indices of bytes to randomize on each packet (0-indexed)
