Method at_inst

cranelift/codegen/src/cursor.rs:86–92

Rebuild this cursor positioned at `inst`. This is intended to be used as a builder method: ``` # use cranelift_codegen::ir::{Function, Block, Inst}; # use cranelift_codegen::cursor::{Cursor, FuncCursor}; fn edit_func(func: &mut Function, inst: Inst) { let mut pos = FuncCursor::new(func).at_inst(inst); // Use `pos`... } ```

(mut self, inst: ir::Inst)

    /// }
    /// ```
    fn at_inst(mut self, inst: ir::Inst) -> Self
    where
        Self: Sized,
    {
        self.goto_inst(inst);
        self
    }

    /// Rebuild this cursor positioned at the first insertion point for `block`.
    /// This differs from `at_first_inst` in that it doesn't assume that any
