Module debug

Available on crate feature debug only.

Debugging support for probe-rs

The debug module contains various debug functionality, which can be used to implement a debugger based on probe-rs.

Re-exports

• pub use self::debug_step::SteppingMode;
• pub use self::stack_frame::StackFrame;
• pub use self::variable_cache::VariableCache;
• pub use self::debug_info::*;
• pub use self::registers::*;
• pub use self::variable::*;

Modules

• debug_info
  Debug information which is parsed from DWARF debugging information.
• debug_step
  Stepping through a program during debug, at various granularities.
• function_die
  References to the DIE (debug information entry) of functions.
• registers
  Target Register definitions, expanded from crate::core::registers::CoreRegister to include unwind specific information.
• stack_frame
  The stack frame information used while unwinding the stack from a specific program counter.
• unit_info
  Information about a Unit in the debug information.
• variable
  Variable information used during debug.
• variable_cache
  The hierarchical cache of all variables for a given scope.

Structs

• SourceLocation
  A specific location in source code. Each unique line, column, file and directory combination is a unique source location.
• VerifiedBreakpoint
  A verified breakpoint represents an instruction address, and the source location that it corresponds to it, for locations in the target binary that comply with the DWARF standard terminology for “recommended breakpoint location”. This typically refers to instructions that are not part of the prologue or epilogue, and are part of the user code, or are the final instruction in a sequence, before the processor begins the epilogue code. The probe-rs debugger uses this information to identify valid halt locations for breakpoints and stepping.

Enums

• ColumnType
  A copy of gimli::ColumnType which uses u64 instead of NonZeroU64.
• DebugError
  An error occurred while debugging the target.
• ObjectRef
  Object reference as defined in the DAP standard.

Functions

• get_object_reference
  Generate a unique key that can be used to assign id’s to StackFrame and Variable structs.

Type Aliases

• EndianReader
  A simplified type alias of the gimli::EndianReader type.
