}Expand description
Trait for types that represent an EVM instruction.
Required Associated Types§
sourcetype ImmediateRef: ?Sized
type ImmediateRef: ?Sized
The return root type of Operation::immediate_mut and
Operation::immediate.
sourcetype Immediate: Borrow<Self::ImmediateRef> + BorrowMut<Self::ImmediateRef>
type Immediate: Borrow<Self::ImmediateRef> + BorrowMut<Self::ImmediateRef>
The type of the immediate argument for this operation.
Required Methods§
sourcefn immediate(&self) -> Option<&Self::ImmediateRef>
fn immediate(&self) -> Option<&Self::ImmediateRef>
Get a shared reference to the immediate argument of this operation, if one exists.
sourcefn immediate_mut(&mut self) -> Option<&mut Self::ImmediateRef>
fn immediate_mut(&mut self) -> Option<&mut Self::ImmediateRef>
Get a mutable reference to the immediate argument of this operation, if one exists.
sourcefn into_immediate(self) -> Option<Self::Immediate>
fn into_immediate(self) -> Option<Self::Immediate>
Consume this operation and return its immediate argument, if one exists.
sourcefn is_jump(&self) -> bool
fn is_jump(&self) -> bool
Returns true if the current instruction changes the program counter (other than incrementing it.)
sourcefn is_jump_target(&self) -> bool
fn is_jump_target(&self) -> bool
Returns true if the current instruction is a valid destination for jumps.
