Function parse_size_from_bytes 

Source
pub fn parse_size_from_bytes(bytes: &[u8]) -> Result<usize, Box<dyn Error>>
Expand description

Parses a byte slice into a usize representing the size of a Git object.

This function is intended to be used for converting the bytes, which represent the size portion in a Git object, back into a usize. This size is typically compared with the actual length of the object’s data part to ensure data integrity.

§Parameters

  • bytes: A byte slice (&[u8]) representing the size in a serialized Git object.

§Returns

Returns a Result which is:

  • Ok(usize): On successful parsing, returns the size as a usize.
  • Err(Box<dyn std::error::Error>): On failure, returns an error in a Box. This error could be due to invalid UTF-8 encoding in the byte slice or a failure to parse the byte slice as a usize.

§Errors

This function handles two main types of errors:

  1. Utf8Error: If the byte slice is not a valid UTF-8 string, which is necessary for the size representation.
  2. ParseIntError: If the byte slice does not represent a valid usize value.
