lib.rs
:
A crate for FixedArray
and FixedString
, types to provide a smaller memory footprint in exchange for:
- Immutablity,
FixedArray
andFixedString
cannot be mutated without converting back to their expanded forms. - Maximum length,
FixedArray
andFixedString
have a length cap ofLenT::MAX
elements.
These types provide cheap conversions to [Vec
] and String
, to make up for most of these downsides, but it is
still not recommended to use these collections for mutated values as you will see a performance downside.
These can be thought of as Box<[T]>
and Box<str>
, except the length is denoted as LenT
, by default [u32
].
