Implementations

impl Terminator

pub fn try_get_result(&self) -> Option<&Name>

Get the result (destination) of the Terminator, or None if the Terminator doesn’t have a result (has void type).

Trait Implementations

impl Clone for Terminator

fn clone(&self) -> Terminator

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Terminator

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

Formats the value using the given formatter.

impl Display for Terminator

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

Formats the value using the given formatter.

impl From<Br> for Terminator

fn from(term: Br) -> Terminator

Converts to this type from the input type.

impl From<CallBr> for Terminator

fn from(term: CallBr) -> Terminator

Converts to this type from the input type.

impl From<CatchRet> for Terminator

fn from(term: CatchRet) -> Terminator

Converts to this type from the input type.

impl From<CatchSwitch> for Terminator

fn from(term: CatchSwitch) -> Terminator

Converts to this type from the input type.

impl HasDebugLoc for Terminator

fn get_debug_loc(&self) -> &Option<DebugLoc>

Returns the DebugLoc associated with the given Instruction, Terminator, GlobalVariable, or Function; or None if it doesn’t have a DebugLoc.

impl PartialEq for Terminator

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

This method tests for self and other values to be equal, and is used by ==.

impl Typed for Terminator

The Type of a Terminator is its result type. For most terminators, this is VoidType. For instance, a Ret instruction has void type even if the function returns a non-void value; we do not store the result of a Ret instruction using something like %3 = ret i32 %2.
