Function load_foundry_creation_code 

pub fn load_foundry_creation_code(path: impl AsRef<Path>) -> DeployResult<Bytes>

Load creation bytecode from a Foundry artifact.

Reads the JSON at path and decodes the creation bytecode from bytecode.object (or the legacy direct-string bytecode field).

Errors

Returns an error when:

• the file cannot be read,
• the contents are not valid JSON,
• the JSON has no bytecode field, or bytecode has neither an object string nor a direct string value,
• the bytecode hex is empty, still contains unresolved library placeholders (__$...$__), or is otherwise not valid hex.
