Function encoding_c::encoding_for_label
[−]
[src]
#[no_mangle]pub unsafe extern fn encoding_for_label(label: *const u8,
label_len: usize)
-> *const Encoding
Implements the get an encoding algorithm.
If, after ASCII-lowercasing and removing leading and trailing
whitespace, the argument matches a label defined in the Encoding
Standard, const Encoding*
representing the corresponding
encoding is returned. If there is no match, NULL
is returned.
The argument buffer can be in any ASCII-compatible encoding. It is not required to be UTF-8.
Undefined behavior
UB ensues if label
and label_len
don't designate a valid memory block.
