tryAcquire
Like TSemaphore.acquire except that it returns whether or not acquisition was successful.
import arrow.fx.stm.TSemaphore
import arrow.fx.stm.atomically
suspend fun main() {
//sampleStart
val tsem = TSemaphore.new(0)
val result = atomically {
tsem.tryAcquire()
}
//sampleEnd
println("Result $result")
println("Permits remaining ${atomically { tsem.available() }}")
}Content copied to clipboard
This function never retries.
See also
for a version that retries if there are not enough permits.
