How to Get Size Of Arbitrary Data In Bytes In Elixir?

July 25, 2024 5:19 AM 2 minutes read

In Elixir, you can get the size of arbitrary data in bytes by utilizing the built-in byte_size/1 function. This function takes a single argument, which can be any data type, and returns the size of the data in bytes. This can be useful when working with binary data, strings, or any other type of data where you need to know the exact size in bytes. Simply call byte_size(data) to get the size of the data in bytes.

How can I calculate the size of arbitrary data in Elixir?

You can calculate the size of arbitrary data in Elixir using the byte_size/1 function. This function takes a binary or string as an argument and returns the number of bytes in that binary or string.

Here's an example:

1
2
3

data = "Hello, world!"
size = byte_size(data)
IO.puts("Size of data: #{size} bytes")

This will output:

1	Size of data: 13 bytes

You can use this function to calculate the size of any arbitrary data in Elixir.

What is the output format for calculating the size of data in bytes in Elixir?

The output format for calculating the size of data in bytes in Elixir is an integer representing the number of bytes.

How to get size of arbitrary data in bytes using Elixir?

To get the size of arbitrary data in bytes in Elixir, you can use the byte_size/1 function.

Here is an example code snippet that demonstrates how to get the size of arbitrary data in bytes:

data = "Hello, World!"
size_in_bytes = byte_size(data)

IO.puts("Size of data in bytes: #{size_in_bytes}")

In this example, the byte_size/1 function is used to calculate the number of bytes required to store the given data. The size is then printed using IO.puts() function.

You can replace the data variable with any arbitrary data (e.g. binary, list, string, etc.) to get its size in bytes.

What is the alternative method to get the byte size of data in Elixir?

Another method to get the byte size of data in Elixir is by using the :erlang.byte_size/1 function. This function takes a binary or string as an argument and returns the byte size of the data.

Example:

1
2
3

data = "Hello, World!"
byte_size = :erlang.byte_size(data)
IO.puts(byte_size) # Output: 13

What is the efficient way to determine the size of data in bytes in Elixir?

One efficient way to determine the size of data in bytes in Elixir is to use the :erlang.byte_size/1 function.

For example:

1
2
3

data = "hello"
size = :erlang.byte_size(data)
IO.puts("Size in bytes: #{size}")

This code snippet will output the size of the string "hello" in bytes.

How to Get Duplicates In A List In Elixir?

To get duplicates in a list in Elixir, you can use the Enum.group_by function to group the elements in the list based on their value. Then, you can filter out the groups that have more than one element, which are the duplicates in the list. Finally, you can ex...

How to Convert Map Entries Into List Of Pair In Elixir?

To convert map entries into a list of pairs in Elixir, you can use the Map.to_list/1 function. This function takes a map as an argument and returns a list of key-value pairs. For example, if you have a map like %{a: 1, b: 2, c: 3}, you can use Map.to_list/1 to...

How to Handle Try And Rescue Errors In Elixir?

In Elixir, a common pattern for handling errors in try and rescue blocks is to use the try keyword to attempt a certain operation and rescue to catch any errors that may occur during the execution.When using try and rescue in Elixir, it is important to be spec...

How to Get Datetime List Using Stream In Elixir?

To get a datetime list using stream in Elixir, you can use the functions in the Stream module such as Stream.cycle and Stream.map.First, you can create a stream of integers using Stream.cycle(1..10) to infinitely cycle through the numbers 1 to 10.Next, you can...

How to Merge Lists Into A List Of Tuples In Elixir?

In Elixir, you can merge multiple lists into a list of tuples using the Enum.zip function. This function takes multiple lists as arguments and returns a new list containing tuples, where each tuple contains elements from corresponding positions in the input li...
