Function message_string_get 

pub fn message_string_get<'a>(
    dest: &'a mut [u8],
    src: &[u8],
    default_src: Option<&str>,
) -> Result<&'a str>

Copies a string from a fixed-size C-style char array within a message to a Rust buffer.

This is a safe wrapper around CFE_SB_MessageStringGet. It correctly handles unterminated strings from the source buffer and ensures the destination is null-terminated.

Arguments

• dest: The mutable byte buffer to copy the string into.
• src: The fixed-size array from the message.
• default_src: An optional default string to use if the source string is empty.
