Associated Types

data WriteVector a

A vector to be written to a flatbuffer.

Methods

fromMonoFoldable

Arguments

:: (MonoFoldable mono, Element mono ~ a)

=> Int32

n: the number of elements in xs

-> mono

xs: a collection

-> WriteVector a

Constructs a flatbuffers vector.

If n is larger than the length of xs, this will result in a malformed buffer. If n is smaller than the length of xs, all elements of xs will still be written to the buffer, but the client will only be able to read the first n elements.

Note: fromMonoFoldable asks for the collection's length to be passed in as an argument rather than use olength because:

1. olength is often O(n), and in some use cases there may be a better way to know the collection's length ahead of time.
2. Calling olength inside fromMonoFoldable can inhibit some fusions which would otherwise be possible.
