Cargo Features

[dependencies]
logos = { version = "0.15.0", default-features = false, features = ["debug", "export_derive", "std", "forbid_unsafe"] }

debug

Enables debug messages

Enables debug of optional logos-derive

default = export_derive, std

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

export_derive default = logos-derive

Re-exports the Logos derive macro, so that end user only needs to import this crate and use logos::Logos to get both the trait and derive proc macro.

std default

Should the crate use the standard library?

forbid_unsafe

Use safe alternatives for unsafe code (may impact performance)?

Enables forbid_unsafe of optional logos-derive

Affects internal::LexerInternal.read_byte, source::Source.read_byte, source::Chunk.from_slice…

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.
