Tryst::SDL::Version
Inherits Comparable < Struct < Value < Object
The version of an SDL library as it is actually loaded at runtime, which is not necessarily the one the shard was compiled against - SDL is a shared library and the two can drift apart.
Constructors
Every SDL3 library reports its version as one packed integer (the SDL_VERSIONNUM macro): major * 1000000 + minor * 1000 + micro. Crystal never reads the headers, so the arithmetic lives here rather than coming from a macro.
Instance methods
The comparison operator. Returns 0 if the two objects are equal,
a negative number if this object is considered less than other,
a positive number if this object is considered greater than other,
or nil if the two objects are not comparable.
Subclasses define this method to provide class-specific ordering.
The comparison operator is usually used to sort values:
# Sort in a descending way:
[3, 1, 2].sort { |x, y| y <=> x } # => [3, 2, 1]
# Sort in an ascending way:
[3, 1, 2].sort { |x, y| x <=> y } # => [1, 2, 3]
