WebSep 9, 2016 · Convert the u8 array to a string first, then call FromStr. Call out to libc's atoi. Write an atoi in Rust. In nearly all cases the first option is reasonable, however there are cases where files maybe be very large, with no predefined encoding... or contain mixed binary and text, where its most straightforward to read integer numbers as bytes. WebSep 10, 2012 · There is a "Byte Array To String" function. If you take your single byte and 'build' it into an array of length=1, then you can convert it to an ASCII character. In this case, type cast is a better option so there is no array building involved.
