[features]

## Default features: `std`, uses runtime random numbers for hashing.

## Standard features: uses compile-time random number for hashing.

#! ### Enable Special Functionalities

    ## Require that all data types implement `Send + Sync` (for multi-threaded usage).
    sync = []
    ## Add support for the [`Decimal`](https://crates.io/crates/rust_decimal) data type (acts as the system floating-point type under `no_float`).
    decimal = ["rust_decimal"]
    ## Enable serialization/deserialization of Rhai data types via [`serde`](https://crates.io/crates/serde).
    serde = ["dep:serde", "smartstring/serde", "smallvec/serde"]
    ## Allow [Unicode Standard Annex #31](https://unicode.org/reports/tr31/) for identifiers.
    unicode-xid-ident = ["unicode-xid"]
    ## Enable functions metadata (including doc-comments); implies [`serde`](#feature-serde).
    metadata = ["serde", "serde_json", "rhai_codegen/metadata", "smartstring/serde"]
    ## Expose internal data structures (e.g. `AST` nodes).
    internals = []
    ## Enable the debugging interface (implies [`internals`](#feature-internals)).
    debugging = ["internals"]
    ## Features and dependencies required by `bin` tools: `decimal`, `metadata`, `serde`, `debugging` and [`rustyline`](https://crates.io/crates/rustyline).
    bin-features = ["decimal", "metadata", "serde", "debugging", "rustyline"]

#! ### System Configuration Features

    ## Use `f32` instead of `f64` as the system floating-point number type.
    f32_float = []
    ## Use `i32` instead of `i64` for the system integer number type (useful for 32-bit architectures).
    ## All other integer types (e.g. `u8`) are disabled.
    only_i32 = []
    ## Disable all integer types (e.g. `u8`) other than `i64`.
    only_i64 = []

#! ### Disable Language Features

    ## Remove support for floating-point numbers.
    no_float = []
    ## Remove support for arrays and indexing.
    no_index = []
    ## Remove support for custom types, properties, method-style calls and object maps.
    no_object = []
    ## Remove support for time-stamps.
    no_time = []
    ## Remove support for script-defined functions (implies [`no_closure`](#feature-no_closure)).
    no_function = ["no_closure"]
    ## Remove support for capturing external variables in anonymous functions (i.e. closures).
    no_closure = []
    ## Remove support for loading external modules.
    no_module = []
    ## Remove support for custom syntax.
    no_custom_syntax = []

#! ### Performance-Related Features

    ## Disable all safety checks.
    unchecked = []
    ## Do not track position when parsing.
    no_position = []
    ## Disable the script optimizer.
    no_optimize = []

#! ### Compiling for `no-std`

    ## Turn on `no-std` compilation (nightly only).
    no_std = ["no-std-compat", "num-traits/libm", "core-error", "libm", "hashbrown", "no_time"]

#! ### JavaScript Interface for WASM

    ## Use [`wasm-bindgen`](https://crates.io/crates/wasm-bindgen) as JavaScript interface.
    wasm-bindgen = ["getrandom/js", "instant/wasm-bindgen"]
    ## Use [`stdweb`](https://crates.io/crates/stdweb) as JavaScript interface.
    stdweb = ["getrandom/js", "instant/stdweb"]
