pub struct OpCode(/* private fields */);Expand description
An EVM opcode
This is always a valid opcode, as declared in the opcode module or the
OPCODE_INFO constant.
Implementations§
Source§impl OpCode
impl OpCode
Sourcepub const fn new(opcode: u8) -> Option<OpCode>
pub const fn new(opcode: u8) -> Option<OpCode>
Instantiates a new opcode from a u8.
Returns None if the opcode is not valid.
Sourcepub const fn is_jumpdest(&self) -> bool
pub const fn is_jumpdest(&self) -> bool
Returns true if the opcode is a jump destination.
Sourcepub const fn is_jumpdest_by_op(opcode: u8) -> bool
pub const fn is_jumpdest_by_op(opcode: u8) -> bool
Takes a u8 and returns true if it is a jump destination.
Sourcepub const fn is_jump_by_op(opcode: u8) -> bool
pub const fn is_jump_by_op(opcode: u8) -> bool
Takes a u8 and returns true if it is a jump instruction.
Sourcepub fn is_push_by_op(opcode: u8) -> bool
pub fn is_push_by_op(opcode: u8) -> bool
Takes a u8 and returns true if it is a push instruction.
Sourcepub unsafe fn new_unchecked(opcode: u8) -> OpCode
pub unsafe fn new_unchecked(opcode: u8) -> OpCode
Instantiates a new opcode from a u8 without checking if it is valid.
§Safety
All code using Opcode values assume that they are valid opcodes, so providing an invalid
opcode may cause undefined behavior.
Sourcepub const fn as_str(self) -> &'static str
pub const fn as_str(self) -> &'static str
Returns the opcode as a string. This is the inverse of parse.
Sourcepub const fn name_by_op(opcode: u8) -> &'static str
pub const fn name_by_op(opcode: u8) -> &'static str
Returns the opcode name.
Sourcepub const fn io_diff(&self) -> i16
pub const fn io_diff(&self) -> i16
Calculates the difference between the number of input and output stack elements.
Sourcepub const fn info_by_op(opcode: u8) -> Option<OpCodeInfo>
pub const fn info_by_op(opcode: u8) -> Option<OpCodeInfo>
Returns the opcode information for the given opcode. Check OpCodeInfo for more information.
Sourcepub const fn info(&self) -> OpCodeInfo
pub const fn info(&self) -> OpCodeInfo
Returns the opcode information.
Sourcepub const fn input_output(&self) -> (u8, u8)
pub const fn input_output(&self) -> (u8, u8)
Returns the number of both input and output stack elements.
Can be slightly faster than calling inputs and outputs separately.
Sourcepub const fn modifies_memory(&self) -> bool
pub const fn modifies_memory(&self) -> bool
Returns true if the opcode modifies memory.
