Crate heed_types

Types that can be used to serialize and deserialize types inside databases.

How to choose the right type to store things in this database? For specific types you can choose:

• Str to store strs
• Unit to store () types
• SerdeBincode or SerdeJson to store Serialize/Deserialize types

But if you want to store big types that can be efficiently deserialized then here is a little table to help you in your quest:

Available types	Encoding type	Decoding type	allocations
CowSlice	&[T]	Cow<[T]>	will allocate if memory is miss-aligned
CowType	&T	Cow<T>	will allocate if memory is miss-aligned
OwnedSlice	&[T]	Vec<T>	will always allocate
OwnedType	&T	T	will always allocate
UnalignedSlice	&[T]	&[T]	will never allocate because alignement is always valid
UnalignedType	&T	&T	will never allocate because alignement is always valid

Structs

• CowSlice
  Describes a slice that must be memory aligned and will be reallocated if it is not.
• CowType
  Describes a type that must be memory aligned and will be reallocated if it is not.
• DecodeIgnore
  A convenient struct made to ignore the type when decoding it.
• I8
• I16
• I32
• I64
• I128
• OwnedSlice
  Describes a Vec of types that are totally owned (doesn’t hold any reference to the original slice).
• OwnedType
  Describes a type that is totally owned (doesn’t hold any reference to the original slice).
• SerdeBincode
  Describes a type that is Serialize/Deserialize and uses bincode to do so.
• SerdeJson
  Describes a type that is Serialize/Deserialize and uses serde_json to do so.
• Str
  Describes an str.
• U8
• U16
• U32
• U64
• U128
• UnalignedSlice
  Describes a type that is totally borrowed and doesn’t depends on any memory alignment.
• UnalignedType
  Describes a slice that is totally borrowed and doesn’t depends on any memory alignment.
• Unit
  Describes the () type.

Type Definitions

• ByteSlice
  Describes a slice of bytes [u8] that is totally borrowed and doesn’t depends on any memory alignment.
