Module fadroma::core::addr

cosmwasm_std::Addr<->cosmwasm_std::CanonicalAddr conversion for types that contain addresses.

Traits

• Address
  Sealed marker trait for types that represent a valid address. Those can only be cosmwasm_std::Addr and cosmwasm_std::CanonicalAddr and thus are the only types that implement the trait.
• Canonize
  The trait that represents any type which contains a cosmwasm_std::Addr and needs to be stored since cosmwasm_std::Addr is usually converted to cosmwasm_std::CanonicalAddr first. The trait must be implemented on the non-canonical version of the type and the output of Canonize::canonize must return the canonical version of the same type which is represented by its sister trait Humanize. This relationship is enforced on the type level since Canonize::Output must implement Humanize and vice versa.
• Humanize
  The trait that represents the canonical version of the given type. See Canonize for more info.
• MaybeAddress
  Sealed marker trait for types that may represent an address. The types that may be a valid address are &str and String since they could potentially contain an address. We use cosmwasm_std::Api::addr_validate or cosmwasm_std::Api::addr_canonicalize to turn them into cosmwasm_std::Addr and cosmwasm_std::CanonicalAddr respectively, both of which definitely do contain a valid address and therefore also satisfy this trait.

Functions

• canonize_maybe_empty
  Attempting to canonicalize an empty address will fail. This function skips calling cosmwasm_std::Api::addr_canonicalize if the input is empty and returns CanonicalAddr::default() instead.
• humanize_maybe_empty
  Attempting to humanize an empty address will fail. This function skips calling cosmwasm_std::Api::addr_humanize if the input is empty and returns Addr::default() instead.
• validate_addresses
  Validates a collection of strings that are expected to be valid addresses.
