Enum SignerAuthorization 

pub enum SignerAuthorization {
    Unregistered,
    Registered {
        cap: u64,
        expiry: u64,
        spent: u64,
    },
}

A voucher signer’s on-chain authorization in one pool, as a node’s admit path and a capability client read it from getAuthorization (ADR 003 §Capability delegation).

Variants

Unregistered

The signer holds no registration (the all-zero Authorization). Its first redemption registers whichever owner-signed capability lands first.

Registered

The signer is registered. cap and expiry are write-once on-chain, so they never change for this (pool, signer); spent only grows.

Fields

cap: u64

The registered spending cap, in micro-USDC.

expiry: u64

The registered expiry, in Unix seconds. The chain treats a voucher at or past it as unredeemable.

spent: u64

What the signer has redeemed across every provider, in micro-USDC.

Implementations

impl SignerAuthorization

pub const fn from_onchain(auth: &Authorization) -> Self

Classify a raw getAuthorization result. The contract marks a signer registered when cap != 0 || expiry != 0, so a registration with a zero cap but a non-zero expiry is registered with no headroom.

pub fn covers(self, floor_micro: U256, now: u64) -> bool

Whether the signer can still pay at least floor_micro at Unix time now. An unregistered signer always can: it admits on its presented capability. A registered signer needs a live registration and cap − spent headroom of at least floor_micro.
