VM configuration settings

Fields

max_call_depth: usize

Maximum call depth

Maximal pc distance after which a new instruction meter validation is emitted by the JIT

enable_instruction_meter: bool

Enable instruction meter and limiting

enable_instruction_tracing: bool

Enable instruction tracing

enable_symbol_and_section_labels: bool

Enable dynamic string allocation for labels

reject_unresolved_syscalls: bool

Reject ELF files containing syscalls which are not in the SyscallRegistry

reject_section_virtual_address_file_offset_mismatch: bool

Reject ELF files containing section headers where sh_addr != sh_offset

noop_instruction_ratio: f64

Ratio of random no-ops per instruction in JIT (0.0 = OFF)

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Config

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

Formats the value using the given formatter.

impl Default for Config

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq<Config> for Config

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

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

fn ne(&self, other: &Config) -> bool

This method tests for !=.
