Operations on byte strings

Variants

Put(u8, Blob)

Put bytestring into a byte string register

Mov(u8, u8)

Move bytestring value between registers

Swp(u8, u8)

Swap bytestring value between registers

Fill(u8, u16, u16, u8)

Fill segment of bytestring with specific byte value

LenS(u8)

Put length of the string into a16[0] register

Count(u8, u8)

Count number of byte occurrences within the string and stores that value in a16[0]

Cmp(u8, u8)

Compare two strings from two registers, putting result into cm0

Comm(u8, u8)

Compute length of the fragment shared between two strings

Find(u8, u8)

Count number of occurrences of one string within another putting result to a16[0]

Extr(Reg32, Reg32, RegBlock, Reg32)

Extract byte string slice into a or r register

Inj(Reg32, Reg32, RegBlock, Reg32)

Inject a a or r value at a given position to string register, replacing value of the corresponding bytes.

Join(u8, u8, u8)

Join bytestrings from two registers

Split(u8, u16, u8, u8)

Split bytestring at a given index into two registers

Ins(u8, u8, u16)

Insert value from one of bytestring register at a given index of other bytestring register, shifting string bytes. If destination register does not fits the length of the new string, its final bytes are removed.

Del(u8, u16, u16)

Delete bytes in a given range, shifting the remaining bytes

Transl(u8, u16, u16, u8)

Extract fragment of bytestring into a register

Trait Implementations

impl Bytecode for BytesOp

fn byte_count(&self) -> u16

Returns number of bytes which instruction and its argument occupies

fn instr_range() -> RangeInclusive<u8>

Returns range of instruction btecodes covered by a set of operations

fn instr_byte(&self) -> u8

Returns byte representing instruction code (without its arguments)

fn write_args<W>(&self, writer: &mut W) -> Result<(), EncodeError> where
    W: Write,
    EncodeError: From<<W as Write>::Error>, 

Writes instruction arguments as bytecode, omitting instruction code byte

impl Clone for BytesOp

fn clone(&self) -> BytesOp

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BytesOp

fn fmt(&self, f: &mut Formatter<'_>) -> Result

fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<BytesOp> for BytesOp

fn eq(&self, other: &BytesOp) -> bool
