Struct SignedTreeHead 

pub struct SignedTreeHead {
    pub event_count: u64,
    pub head: Option<String>,
    pub signature: String,
}

An Ed25519-signed commitment to a log’s chain head — a publicly-verifiable tree head.

Strict deserialization (deny_unknown_fields): a signed head is a security artifact whose signature covers only (event_count, head) — an unknown field in a stored/published head is unsigned noise at best and tampering at worst, so it fails loudly instead of being silently dropped.

Fields

event_count: u64

head: Option<String>

Lowercase-hex head digest, or None for an empty log.

signature: String

Lowercase-hex Ed25519 signature over the framed (count, head) message.
