Struct Mapping

pub struct Mapping {
    pub iid: Option<u64>,
    pub build_id: Option<u64>,
    pub exact_offset: Option<u64>,
    pub start_offset: Option<u64>,
    pub start: Option<u64>,
    pub end: Option<u64>,
    pub load_bias: Option<u64>,
    pub path_string_ids: Vec<u64>,
}

Fields

iid: Option<u64>

Interning key.

build_id: Option<u64>

Interning key.

exact_offset: Option<u64>

This is not set on Android 10.

start_offset: Option<u64>

start: Option<u64>

end: Option<u64>

load_bias: Option<u64>

Libunwindstack-specific concept, not to be confused with bionic linker’s notion of load_bias. Needed to correct relative pc addresses (as produced by libunwindstack) when doing offline resymbolisation.

For an executable ELF PT_LOAD segment, this is: p_vaddr - p_offset

Where p_offset means that the code is at that offset into the ELF file on disk. While p_vaddr is the offset at which the code gets mapped, relative to where the linker loads the ELF into the address space. For most ELFs, the two values are identical and therefore load_bias is zero.

path_string_ids: Vec<u64>

E.g. [“system”, “lib64”, “libc.so”] id of string.

Implementations

impl Mapping

pub fn iid(&self) -> u64

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

pub fn build_id(&self) -> u64

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

pub fn start_offset(&self) -> u64

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

pub fn start(&self) -> u64

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

pub fn end(&self) -> u64

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

pub fn load_bias(&self) -> u64

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

pub fn exact_offset(&self) -> u64

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

Trait Implementations

impl Clone for Mapping

fn clone(&self) -> Mapping

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mapping

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

Formats the value using the given formatter.

impl Default for Mapping

fn default() -> Self

Returns the “default value” for a type.

impl Message for Mapping

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 Mapping

fn eq(&self, other: &Mapping) -> 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.
