Struct CodeRange

pub struct CodeRange {
    pub base_address: Option<u64>,
    pub size: Option<u64>,
    pub embedded_blob_code_copy_start_address: Option<u64>,
    pub is_process_wide: Option<bool>,
}

A code range is a virtual memory cage that may contain executable code. Depending on the Isolate settings the Isolate might have one or not. See: https://source.chromium.org/chromium/chromium/src/+/main:v8/src/heap/code-range.h If the isolate defines code range this will be tracked here.

Fields

base_address: Option<u64>

size: Option<u64>

embedded_blob_code_copy_start_address: Option<u64>

Used when short builtin calls are enabled, where embedded builtins are copied into the CodeRange so calls can be nearer.

is_process_wide: Option<bool>

Whether this code range is shared with other Isolates in the same process

Implementations

impl CodeRange

pub fn base_address(&self) -> u64

Returns the value of base_address, or the default value if base_address is unset.

pub fn size(&self) -> u64

Returns the value of size, or the default value if size is unset.

pub fn embedded_blob_code_copy_start_address(&self) -> u64

Returns the value of embedded_blob_code_copy_start_address, or the default value if embedded_blob_code_copy_start_address is unset.

pub fn is_process_wide(&self) -> bool

Returns the value of is_process_wide, or the default value if is_process_wide is unset.

Trait Implementations

impl Clone for CodeRange

fn clone(&self) -> CodeRange

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CodeRange

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

Formats the value using the given formatter.

impl Default for CodeRange

fn default() -> Self

Returns the “default value” for a type.

impl Message for CodeRange

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for CodeRange

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
