Module dotns 

Pure DOTNS encoding and decoding functions.

No I/O. No network calls. WASM-safe.

Provides ENS-style namehashing, ABI encoding, SCALE encoding/decoding, and contenthash → CID conversion for the DOTNS resolver protocol.

Constants

CONTENTHASH_SELECTOR

Solidity function selector for contenthash(bytes32).

Functions

base32_encode

RFC 4648 base32 encoding (lowercase, no padding).

contenthash_to_cid

Parse a contenthash value to extract an IPFS CIDv1.

decode_abi_bytes

Decode ABI-encoded bytes return value from Solidity.

decode_contract_result

Decode the SCALE-encoded ContractResult from pallet-revive’s ReviveApi::call.

decode_scale_compact

Decode a SCALE compact-encoded integer, returning (value, bytes_consumed).

decode_unsigned_varint

Decode an unsigned varint (LEB128), returning (value, bytes_consumed).

encode_contenthash_call

ABI-encode contenthash(bytes32 node) call data.

hex_addr

Compile-time hex string to 20-byte address.

hex_nibble

Compile-time hex character to nibble value.

keccak256

Compute keccak256 hash of the given data.

namehash

ENS-style namehash: namehash("mytestapp.dot").

scale_compact_len

SCALE compact encoding for a length prefix.

scale_compact_u64

SCALE compact encoding for a u64 value.

scale_encode_revive_call

SCALE-encode the parameters for ReviveApi::call() runtime API.
