erc7730.generate.schema_tree.abi_function_to_tree(function: Function) → SchemaStruct | SchemaArray | SchemaLeafView on GitHub

Convert a function ABI to a schema tree.

A schema tree is a tree representation of the ABI of a function inputs, enriched with some metadata to ease crafting paths to access values in the serialized calldata.

Parameters:

function – function ABI

Returns:

Schema tree

erc7730.generate.schema_tree.eip712_schema_to_tree(schema: EIP712Schema) → SchemaStruct | SchemaArray | SchemaLeafView on GitHub

Convert an EIP-712 schema to a schema tree.

A schema tree is a tree representation of the EIP-712 schema, enriched with some metadata to ease crafting paths to access values in the message.

Parameters:

schema – EIP-712 schema

Returns:

Schema tree
