Instance Method Detail

def bytes : Slice(T) #

Returns binary raw array of expecting type.

Raises NilAssertionError if #fetch_ptr returns NULL.

def bytes? : Slice(T)? #

Returns binary raw array of expecting type.

Returns nil if #fetch_ptr returns NULL.

abstract def fetch_ptr : Pointer(T) #

We needs a method to get pointer data.

def to_a : Array(T) #

Returns the array of values using #bytes

This may be faster than Indexable#to_a
