Overview

A Slice is a Pointer with an associated size.

While a pointer is unsafe because no bound checks are performed when reading from and writing to it, reading from and writing to a slice involve bound checks. In this way, a slice is a safe alternative to Pointer.

A Slice can be created as read-only: trying to write to it will raise. For example the slice of bytes returned by String#to_slice is read-only.

Instance Method Summary

• #concat(other : self, count : Int) : self
• #concat(other : Pointer(T), count : Int) : self
• #concat(other : self) : self
• #skip(& : T -> Bool) : self
• #take_while(& : T -> Bool) : self

  Passes elements to the block until the block returns a falsey value, then stops iterating and returns an Array of all prior elements.

• #unsafe_index(byte : Int) : Int32 | Nil
• #unsafe_index(*bytes : Int) : Int32 | Nil
