Function read_str

nodedb-query/src/msgpack_scan/reader.rs:271–275

Read a string slice from the value at `offset`. Zero-copy — borrows directly from the input buffer. Returns `None` for non-string types or invalid UTF-8.

(buf: &[u8], offset: usize)

/// directly from the input buffer. Returns `None` for non-string types
/// or invalid UTF-8.
pub fn read_str(buf: &[u8], offset: usize) -> Option<&str> {
    let (start, len) = str_bounds(buf, offset)?;
    let bytes = buf.get(start..start + len)?;
    str::from_utf8(bytes).ok()
}

/// Read a string slice at `*off`, advancing `*off` past it. Zero-copy.
/// Returns `None` for non-string types, invalid UTF-8, or truncated input.
