Struct IcpEventInit 

pub struct IcpEventInit {
    pub v: VersionString,
    pub d: Said,
    pub i: Prefix,
    pub s: KeriSequence,
    pub kt: Threshold,
    pub k: Vec<CesrKey>,
    pub nt: Threshold,
    pub n: Vec<Said>,
    pub bt: Threshold,
    pub b: Vec<Prefix>,
    pub c: Vec<ConfigTrait>,
    pub a: Vec<Seal>,
}

Parameter struct for IcpEvent::new. Mirrors the existing field set 1-for-1 so call-site migration is a mechanical prefix/ suffix wrap. Future wire-format additions land on IcpEvent via a with_* method, not by widening this Init struct — that’s what makes the pattern future-proof.

Fields

v: VersionString

Version string (KERI10JSON…); a placeholder until finalized.

d: Said

Self-addressing identifier (the event SAID); blank until finalized.

i: Prefix

Identifier prefix; for inception this equals the SAID (self-addressing).

s: KeriSequence

Sequence number (0 for inception).

kt: Threshold

Signing threshold over the current keys k.

k: Vec<CesrKey>

Current signing keys (CESR-encoded verkeys).

nt: Threshold

Next-key threshold over the pre-rotation commitments n.

n: Vec<Said>

Pre-rotation commitments (digests of the next keys).

bt: Threshold

Backer (witness) threshold.

b: Vec<Prefix>

Backer (witness) prefixes.

c: Vec<ConfigTrait>

Configuration traits (e.g. establishment-only, do-not-delegate).

a: Vec<Seal>

Anchored seals.
