Instance Method Detail

def bytes_since_gc : UInt64Source

Total memory allocated by the GC into its HEAP since the last GC collection, in bytes.

def cloneSource

DEPRECATED

def copy_with(heap_size = @heap_size, free_bytes = @free_bytes, unmapped_bytes = @unmapped_bytes, bytes_since_gc = @bytes_since_gc, total_bytes = @total_bytes)Source

DEPRECATED

def free_bytes : UInt64Source

Approximate number of free bytes in the GC HEAP. The number is relative to the #heap_size. The reported value is pessimistic, there might be more free bytes in reality.

def heap_size : UInt64Source

The system memory allocated by the GC for its HEAP, in bytes. The memory may or may not have been allocated by the OS (for example some pages haven't been accessed). The number can grow and shrink as needed by the process.

def total_bytes : UInt64Source

Total memory allocated by the GC into its HEAP since the program started, in bytes. The number keeps growing indefinitely until the integer wraps back to zero.

def unmapped_bytes : UInt64Source

The size (in bytes) of virtual system memory that the GC returned to the OS when shrinking its HEAP. The OS may have reclaimed the memory already, reducing the resident memory usage, or may do so later (for example on memory pressure). The GC will reuse this memory when it needs to grow its HEAP again.
