run
Calls block with this value as its receiver and returns its result.
Inside the block, this refers to this value. Nullable receivers are passed through; a safe call skips the block when the receiver is null. The block runs once; its exceptions propagate and it supports non-local returns.
Receiver
value available as this in the block.
Return
the value produced by block.
Parameters
block
computation to run once.
Type Parameters
T
type of the receiver, which may be nullable.
R
type of the block result.
