Module subxt_core::utils

Miscellaneous utility helpers.

Modules

• bits
  Generic scale_bits over bitvec-like BitOrder and BitFormat types.

Structs

• AccountId32
  A 32-byte cryptographic identifier. This is a simplified version of Substrate’s sp_core::crypto::AccountId32. To obtain more functionality, convert this into that type.
• Encoded
  Wraps an already encoded byte vector, prevents being encoded as a raw byte vector as part of the transaction payload
• H160
  Fixed-size uninterpreted hash type with 20 bytes (160 bits) size.
• H256
  Fixed-size uninterpreted hash type with 32 bytes (256 bits) size.
• H512
  Fixed-size uninterpreted hash type with 64 bytes (512 bits) size.
• Static
  If the type inside this implements Encode, this will implement scale_encode::EncodeAsType. If the type inside this implements Decode, this will implement scale_decode::DecodeAsType.
• UncheckedExtrinsic
  The unchecked extrinsic from substrate.
• WrapperKeepOpaque
  A wrapper for any type T which implement encode/decode in a way compatible with Vec<u8>. WrapperKeepOpaque stores the type only in its opaque format, aka as a Vec<u8>. To access the real type T Self::try_decode needs to be used.
• Yes
  A unit marker struct.

Enums

• Era
  An era to describe the longevity of a transaction.
• MultiAddress
  A multi-format address wrapper for on-chain accounts. This is a simplified version of Substrate’s sp_runtime::MultiAddress. To obtain more functionality, convert this into that type (this conversion functionality is provided via From impls if the substrate-compat feature is enabled).
• MultiSignature
  Signature container that can store known signature types. This is a simplified version of sp_runtime::MultiSignature. To obtain more functionality, convert this into that type.

Functions

• strip_compact_prefix
  Decodes a compact encoded value from the beginning of the provided bytes, returning the value and any remaining bytes.
• to_hex
  A quick helper to encode some bytes to hex.

Type Aliases

• KeyedVec
  This represents a key-value collection and is SCALE compatible with collections like BTreeMap. This has the same type params as BTreeMap which allows us to easily swap the two during codegen.
