[−][src]Function lexical_core::atousize_range
#[no_mangle]pub unsafe extern "C" fn atousize_range(
first: *const u8,
last: *const u8
) -> usize
Unchecked parser for a string-to-number conversion using pointer ranges.
Returns the parsed value, ignoring any trailing invalid digits, and explicitly wrapping on arithmetic overflow.
This parser is FFI-compatible, and therefore may be called externally from C code.
first
- Pointer to the start of the input data.last
- Pointer to the one-past-the-end of the input data.
Panics
Panics if either pointer is null.
