Struct mz_prof::pprof_types::Location

pub struct Location {
    pub id: u64,
    pub mapping_id: u64,
    pub address: u64,
    pub line: Vec<Line>,
    pub is_folded: bool,
}

Describes function and line table debug information.

Fields

id: u64

Unique nonzero id for the location. A profile could use instruction addresses or any integer sequence as ids.

mapping_id: u64

The id of the corresponding profile.Mapping for this location. It can be unset if the mapping is unknown or not applicable for this profile type.

address: u64

The instruction address for this location, if available. It should be within [Mapping.memory_start…Mapping.memory_limit] for the corresponding mapping. A non-leaf address may be in the middle of a call instruction. It is up to display tools to find the beginning of the instruction if necessary.

line: Vec<Line>

Multiple line indicates this location has inlined functions, where the last entry represents the caller into which the preceding entries were inlined.

E.g., if memcpy() is inlined into printf: line[0].function_name == “memcpy” line[1].function_name == “printf”

is_folded: bool

Provides an indication that multiple symbols map to this location’s address, for example due to identical code folding by the linker. In that case the line information above represents one of the multiple symbols. This field must be recomputed when the symbolization state of the profile changes.

Trait Implementations

impl Clone for Location

fn clone(&self) -> Location

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Location

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

Formats the value using the given formatter.

impl Default for Location

fn default() -> Self

Returns the “default value” for a type.

impl Message for Location

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(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where 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( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where 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(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

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

where Self: Default,

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

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

where Self: Sized,

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

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

where Self: Sized,

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

impl PartialEq for Location

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