Generic Instance Method

flatMap(_:)

Generates an array containing the non-nil results of calling the given transformation with each byte of the digest.

Declaration

func flatMap<ElementOfResult>(_ transform: (UInt8) throws -> ElementOfResult?) rethrows -> [ElementOfResult]

Parameters

transform

A closure that accepts a byte of the digest as its argument and returns an optional value.

Return Value

An array of the non-nil results of calling transform with each byte of the digest.
