BitReader is a helper type to extract strings of bits from a slice of bytes.
Here is how you read first a single bit, then three bits and finally four bits from a byte buffer:
use bitreader::BitReader; let slice_of_u8 = &[0b1000_1111]; let mut reader = BitReader::new(slice_of_u8); // You obviously should use try! or some other error handling mechanism here let a_single_bit = reader.read_u8(1).unwrap(); // 1 let more_bits = reader.read_u8(3).unwrap(); // 0 let last_bits_of_byte = reader.read_u8(4).unwrap(); // 0b1111
You can naturally read bits from longer buffer of data than just a single byte.
As you read bits, the internal cursor of BitReader moves on along the stream of bits. Big endian format is assumed when reading the multi-byte values. BitReader supports reading maximum of 64 bits at a time (with read_u64).
