Modules

data_source

data_source module — mirrors graph-ts dataSource

Macros

debug

error

info

Logging macros matching graph-ts log levels

warning

Structs

Address

20-byte Ethereum address.

BigDecimal

BigInt

Contract

Bound contract for making eth_call.

DataSourceContext

DataSourceContext — per-instance configuration passed via createWithContext. Mirrors graph-ts DataSourceContext: typed key-value store.

Entity

EntityCache

Log

Trigger data passed to native handlers. Represents an Ethereum log entry with transaction/block context. In production, this is populated from graph-node’s trigger data.

Enums

BigIntSign

A Sign is a BigInt’s composing element.

DecodedParam

A decoded event parameter value.

EntityIdValue

Value

Traits

HandlerContext

IntoEntityValue

Functions

abi_decode

Decode ABI-encoded bytes using a Solidity type signature string. Mirrors graph-ts ethereum.decode(signature, data).

bytes_from_hex_string

Decode a hex string into bytes. Mirrors graph-ts Bytes.fromHexString(). Accepts with or without 0x/0X prefix. Panics on invalid hex input — matches graph-ts strict behavior.

bytes_from_utf8

Convert a UTF-8 string into bytes. Mirrors graph-ts Bytes.fromUTF8().

bytes_to_hex_id

bytes_to_value

concat_bytes

Concatenate two byte arrays — used for entity ID generation. Mirrors graph-ts Bytes.concat()

concat_i32

Concatenate bytes with an i32 suffix — used for entity ID generation. Mirrors graph-ts Bytes.concatI32(): appends 4 little-endian bytes of the i32 to the byte array, returns 0x-prefixed hex string.

decode_event_params

Decode event parameters from a log entry using its JSON ABI definition.
