Decompresses string. Raises a Zlib::NeedDict exception if a preset dictionary is needed for decompression.
This method is almost equivalent to the following code:
def inflate(string) zstream = Zlib::Inflate.new buf = zstream.inflate(string) zstream.finish zstream.close buf end

Return true if the named file exists.
file_name can be an IO object.
“file exists” means that stat() or fstat() system call is successful.
Deprecated method. Don’t use.
Returns true if the named file is writable by the effective user and group id of this process. See eaccess(3).
Returns true if the named file is a symbolic link.
Returns true if the named file has the sticky bit set.
file_name can be an IO object.
Initiates garbage collection, unless manually disabled.
This method is defined with keyword arguments that default to true:
def GC.start(full_mark: true, immediate_sweep: true); end
Use full_mark: false to perform a minor GC. Use immediate_sweep: false to defer sweeping (use lazy sweep).
Note: These keyword arguments are implementation and version dependent. They are not guaranteed to be future-compatible, and may be ignored if the underlying implementation does not support them.
Returns a Hash containing information about the GC.
The hash includes information about internal statistics about GC such as:
{
:count=>0,
:heap_allocated_pages=>24,
:heap_sorted_length=>24,
:heap_allocatable_pages=>0,
:heap_available_slots=>9783,

:heap_tomb_pages=>0,
:total_allocated_pages=>24,
:total_freed_pages=>0,

}
The contents of the hash are implementation specific and may be changed in the future.
