[dependencies]
ink_env = { version = "6.0.0-alpha", default-features = false, features = ["std", "ink-debug", "no-allocator", "no-panic-handler", "unstable-hostfn"] }

default = std

The std feature is set by default whenever ink_env is added without default-features = false somewhere in the dependency tree.

std default = blake2, scale-decode, scale-encode, schnorrkel, secp256k1, sha2, sha3

Enables std of derive_more, ink_allocator, ink_engine, ink_prelude, ink_primitives, ink_storage_traits, num-traits, parity-scale-codec, optional scale-decode ^0.14.0, optional scale-encode ^0.8.0, scale-info, sp-io, sp-runtime-interface, and staging-xcm

Affects api::return_value, backend::EnvBackend.return_value…

ink-debug

Enable contract debug messages via debug_print! and debug_println!.

no-allocator

Disable the ink! provided global memory allocator.

Enables no-allocator of ink_allocator

no-panic-handler

Disable the ink! provided panic handler.

unstable-hostfn

Affects api::account_id, api::minimum_balance, api::take_contract_storage, api::contains_contract_storage, api::clear_contract_storage, api::instantiate_contract, api::terminate_contract, api::ecdsa_to_eth_address, api::sr25519_verify, api::is_contract, api::own_code_hash, api::caller_is_origin, api::caller_is_root, api::set_code_hash, api::call_runtime, api::xcm_execute, backend::EnvBackend.take_contract_storage, backend::EnvBackend.contains_contract_storage, backend::EnvBackend.clear_contract_storage, backend::EnvBackend.ecdsa_to_eth_address…

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
