struct Cradare2::Model::Registers

• Cradare2::Model::Registers
• Struct
• Value
• Object

Overview

Represents CPU registers returned by radare2 drj. Provides architecture-agnostic helpers for instruction pointer and stack pointer, as well as named accessors for x86/x64/ARM registers.

Included Modules

• JSON::Serializable

Defined in:

cradare2/models/register.cr

Constructors

• .new(pull : JSON::PullParser)
• .new(registers : Hash(String, UInt64) = Hash(String, UInt64).new)

  For direct instantiation in tests/mocks

• .new(*, __pull_for_json_serializable pull : JSON::PullParser)

Instance Method Summary

• #[](name : String) : UInt64

  Fetches any register by name (case-insensitive)

• #[]?(name : String) : UInt64 | Nil

  Safe lookup returning nil if register is absent

• #all_registers : Hash(String, UInt64)

  Returns all captured registers

• #bp : UInt64

• #sp : UInt64

  Architecture-neutral Stack Pointer (RSP on x64, ESP on x86, SP on ARM)

• #values : Hash(String, UInt64)

  Captures all key-value registers from the JSON payload
