@@ -7,14 +7,17 @@ Use Only One Integer Type
------------------------
Some features are for performance. For example, using [`only_i32`] or [`only_i64`] disables all other integer types (such as `u16`).
If only a single integer type is needed in scripts - most of the time this is the case - it is best to avoid registering
lots of functions related to other integer types that will never be used. As a result, performance should improve.
lots of functions related to other integer types that will never be used. As a result, [`Engine`] creation will be faster
because fewer functions need to be loaded.
Use Only 32-Bit Numbers
----------------------
If only 32-bit integers are needed - again, most of the time this is the case - using [`only_i32`] disables also `i64`.
On 64-bit targets this may not gain much, but on some 32-bit targets this improves performance due to 64-bit arithmetic
requiring more CPU cycles to complete.
@@ -24,4 +27,5 @@ Minimize Size of [`Dynamic`]
Turning on [`no_float`], and [`only_i32`] makes the key [`Dynamic`] data type only 8 bytes small on 32-bit targets
while normally it can be up to 16 bytes (e.g. on x86/x64 CPU's) in order to hold an `i64` or `f64`.
Making [`Dynamic`] small helps performance due to better cache efficiency.
