# Enable nightly-only features like better compiler diagnostics and a Parser impl for ! (the never type).

# Allows deeper recursion by dynamically spilling stack state on to the heap.
spill-stack = ["dep:stacker", "std"]

# Allows parser memoization, speeding up heavily back-tracking parsers and allowing left recursion.
memoization = []

# Allows extending chumsky by writing your own parser implementations.
extension = []

# Enable support for parser labelling
label = []

# Make builtin parsers such as `Boxed` use atomic instead of non-atomic internals.
sync = ["spin"]

# Enable Pratt parsing combinator
pratt = ["unstable"]

# Allow the use of unstable features (aka features where the API is not settled)
unstable = []

# Allows use of the `Number` parser, which is backed by the `lexical` crate
lexical-numbers = ["lexical", "unstable"]

# Adds impl of Parser for either::Either
either = ["dep:either"]

# Enables regex combinators
regex = ["dep:regex-automata"]

# Enable serde serialization support
serde = ["dep:serde"]

# An alias of all features that work with the stable compiler.
# Do not use this feature, its removal is not considered a breaking change and its behaviour may change.
# If you're working on chumsky and you're adding a feature that does not require nightly support, please add it to this list.
