Context

Holds the background context, which is never cancelled and is the root of all others.

Syntax

Context( )

Notes

• the background context; never cancelled

Examples

#import "std/tasks"
using tasks

'' The background context: never cancelled, and the root every other
'' context descends from
dim ctx as Context

print ctx.IsCancelled( )     '' false
print "[" & ctx.Err( ) & "]" '' [] -- empty while it is still live

'' NOTHING IS EVER KILLED. Cancellation is a request a goroutine
'' notices, or does not. TerminateThread would skip destructors and
'' DEFER blocks and leak every mutex the thread held -- in a language
'' with DEFER, forced termination misses exactly the cleanup that was
'' written to be unmissable.
