Cargo Features

[dependencies]
ink_env = { version = "5.0.0", default-features = false, features = ["std", "ink-debug", "no-allocator"] }

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 ink_allocator, ink_engine, ink_prelude, ink_primitives, ink_storage_traits, num-traits, parity-scale-codec, and scale-info

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

Features from optional dependencies
