Features

FeatureDescriptionDefault?Should not be used with Rhai feature
floatenables random floating-point number generationyesno_float
arrayenables methods for arraysyesno_index
metadataenables functions metadata (turns on metadata in Rhai)no

Example: Working with no_float in Rhai

Cargo.toml:

[dependencies]
# Rhai is set for 'no_float', meaning no floating-point support
rhai = { version="1.12.0", features = ["no_float"] }

# Use 'default-features = false' to clear defaults, then only add 'array'
rhai-rand = { version="0.1", default-features = false, features = ["array"] }
