rustHow to convert a Rust slice of u8 to u32?


To convert a Rust slice of u8 to u32, you can use the from_le_bytes method from the std::convert::TryInto trait. This method takes a slice of u8 and returns a u32.

Example code

let bytes = [0x01, 0x02, 0x03, 0x04];
let result: u32 = u32::from_le_bytes(bytes);

Output example

result: u32 = 16909060

Code explanation

  • let bytes = [0x01, 0x02, 0x03, 0x04];: This line creates a slice of u8 with the values 0x01, 0x02, 0x03, 0x04.
  • let result: u32 = u32::from_le_bytes(bytes);: This line uses the from_le_bytes method from the std::convert::TryInto trait to convert the slice of u8 to a u32.
