Crate xet_runtime 

Async runtime, configuration, logging, and utility infrastructure for the Hugging Face Xet storage tools.

Macros

all_config_groups

Single source of truth for all platform-independent config groups. Invokes the given callback macro with the list of group names.

config_group

Macro to create a configuration value group struct.

test_configurable_constants

test_set_config

A macro for tests that sets config group environment variables before XetRuntime is initialized. The environment variables follow the pattern HF_XET_{GROUP_NAME}_{FIELD_NAME}.

test_set_constants

A macro for tests that sets HF_XET_<CONSTANT_NAME> to $value before the constant is initialized, and then checks that the constant actually picks up that value. If the constant was already accessed (thus initialized), or if it doesn’t match after being set, this macro panics.
