 # Overview of StructArrays.jl
 
-This package introduces the type `StructArray` which is an `AbstractArray` whose elements are `struct` (for example `NamedTuples`,  or `ComplexF64`, or a custom user defined `struct`). While a `StructArray` iterates `structs`, the layout uses separate arrays for each field of the `struct`. This is often called [Structure-Of-Arrays (SOA)](https://en.wikipedia.org/wiki/AoS_and_SoA); the concepts will be explained in greater detail below. `struct` entries of a StructArray are constructed on-the-fly. This contrasts with the "Array-Of-Structs" (AOS) layout where individual array elements are explicitly stored as `struct`s.

 The package was largely inspired by the `Columns` type in [IndexedTables](https://github.com/JuliaComputing/IndexedTables.jl) which it now replaces.

 ## Using custom array types
 
-StructArrays supports using custom array types. It is always possible to pass field arrays of a custom type. The "custom array of structs to struct of custom arrays" transformation will use the `similar` method of the custom array type. This can be useful when working on the GPU for example:

 ## Lazy row iteration
 
-StructArrays also provides a `LazyRow` wrapper for lazy row iteration. `LazyRow(t, i)` does not materialize the i-th row but returns a lazy wrapper around it on which `getproperty` does the correct thing. This is useful when the row has many fields only some of which are necessary. It also allows changing columns in place.
