pub struct ErrorHandlerStack { /* private fields */ }Expand description
Keeps track of error handlers pushed during evaluation of an IR block.
Implementations§
Source§impl ErrorHandlerStack
impl ErrorHandlerStack
pub const fn new() -> ErrorHandlerStack
Sourcepub fn push(&mut self, handler: ErrorHandler)
pub fn push(&mut self, handler: ErrorHandler)
Push a new error handler onto the stack.
Sourcepub fn pop(&mut self, base: usize) -> Option<ErrorHandler>
pub fn pop(&mut self, base: usize) -> Option<ErrorHandler>
Try to pop an error handler from the stack. Won’t go below base, to avoid retrieving a
handler belonging to a parent frame.
Sourcepub fn leave_frame(&mut self, base: usize)
pub fn leave_frame(&mut self, base: usize)
Reset the stack to the state it was in at the beginning of the frame, in preparation to return control to the parent frame.
