Module cgl_rs::utils

This module contains CGL utility functions, as well some miscellaneous functions.

Functions

• append_file
  Arguments
• append_string_to_file
  Appends a string to a file.
• big_endian_to_current
  Converts a slice of u8 values from big-endian byte order to the system’s native byte order.
• crc32
  Calculates the CRC32 checksum of the given data.
• crc64
  The C implementation is based on linux’s crc64 implementation.
• fast_rand
  Generates a fast random number.
• fast_srand
  Sets the seed for the fast random number generator.
• get_file_size
  Returns the size of a file in bytes.
• get_random_with_probability
  Returns a random index from the given slice of probabilities, where the probability of each index being chosen is proportional to its value in the slice.
• get_time
  Returns the time in seconds since the program started.
• get_timestamp
  Returns a string representing the current timestamp.
• is_little_endian
  Returns a boolean indicating whether the system is little-endian or not.
• lerp
  Linearly interpolates between two values.
• little_endian_to_current
  Converts a slice of u8 values from little-endian byte order to the system’s native byte order.
• map
  Maps a value from one range to another.
• rand31
  Generates a random number using the rand31 algorithm.
• random_float
  Generates a random floating-point number between 0 and 1.
• random_float_range
  Generates a random floating-point number within the given range.
• random_int
  Generates a random integer within the given range.
• read_file
  Reads the contents of a file and returns it as a vector of bytes.
• read_file_as_string
  Reads the contents of a file and returns it as a string.
• reverse_bytes
  Reverses the order of bytes in the given slice of u8 values.
• rot13
  Applies the ROT13 substitution cipher to the given string.
• sleep
  Suspends the current thread for the specified amount of time.
• srand31
  Sets the seed for the rand31 random number generator.
• super_fast_hash
  Calculates the SuperFastHash of the given data.
• write_file
  Arguments
• write_string_to_file
  Writes a string to a file.
• xorshf96
  Generates a fast random number using the xorshf96 algorithm.
