Cargo Features

[dependencies]
deno_core = { version = "0.319.0", default-features = false, features = ["include_icu_data", "v8_use_custom_libcxx", "unsafe_runtime_options", "snapshot_flags_eager_parse"] }
default = include_icu_data, v8_use_custom_libcxx

These default features are set whenever deno_core is added without default-features = false somewhere in the dependency tree.

include_icu_data default = deno_core_icudata
v8_use_custom_libcxx default

Enables use_custom_libcxx of v8

include_js_files_for_snapshotting unsafe_runtime_options
unsafe_use_unprotected_platform snapshot_flags_eager_parse

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.
