Crate cw_utils

This is a collection of common types shared among many specs. For example Expiration, which is embedded in many places.

Types should only be added here after they are duplicated in a second contract, not “because we might need it”

Structs

• MsgExecuteContractResponse
• MsgInstantiateContractResponse
• NativeBalance

Enums

• Duration
  Duration is a delta of time. You can add it to a BlockInfo or Expiration to move that further in the future. Note that an height-based Duration and a time-based Expiration cannot be combined
• Expiration
  Expiration represents a point in time when some event happens. It can compare with a BlockInfo and will return is_expired() == true once the condition is hit (and for every block in the future)
• ParseReplyError
• PaymentError
• Scheduled
  Scheduled represents a point in time when an event happens. It can compare with a BlockInfo and will return is_triggered() == true once the condition is hit (and for every block in the future)
• Threshold
  This defines the different ways tallies can happen.
• ThresholdError
• ThresholdResponse
  This defines the different ways tallies can happen. Every contract should support a subset of these, ideally all.

Constants

• DAY
• HOUR
• WEEK

Functions

• calc_range_end
• calc_range_start
• calc_range_start_string

  Similar to must_pay, but it any payment is optional. Returns an error if a different denom was sent. Otherwise, returns the amount of denom sent, or 0 if nothing sent.
• maybe_addr
• maybe_canonical
• must_pay
  Requires exactly one denom sent, which matches the requested denom. Returns the amount if only one denom and non-zero amount. Errors otherwise.
• nonpayable
  returns an error if any coins were sent
• one_coin
  If exactly one coin was sent, returns it regardless of denom. Returns error if 0 or 2+ coins were sent
• parse_execute_response_data
• parse_instantiate_response_data
