Campaign

Campaign holds the state of a single crowdfunding campaign. It carries no ID field: the id belongs to the store, which hands it back on lookup and iteration.

campaigns

campaigns assigns the campaign ids. v0 kept its own nextID plus a key() that zero-padded to width 12, which stopped ordering Render past 10^12, and its own mustGet whose panic did not say which campaign was missing.

mustGet

Launch

Launch creates a new campaign owned by the caller and returns its id.

Pledge

Pledge backs campaign id with amount (before the deadline).

Unpledge

Unpledge withdraws amount from the caller's pledge (before the deadline).

Claim

Claim lets the creator take the funds if the goal was met after the deadline.

Refund

Refund returns the caller's pledge if the campaign failed after the deadline.

pct

pct returns the funded percentage (0..100).

progressBar
