Mojo module

info

Implements methods for querying the host target info.

You can import these APIs from the sys package. For example:

from sys import is_x86
from sys import is_x86

Functions​

  • ​alignof: Returns the align of (in bytes) of the type.
  • ​bitwidthof: Returns the size of (in bits) of the type.
  • ​has_avx: Returns True if the host system has AVX, otherwise returns False.
