Struct Frame 

pub struct Frame {
    pub iid: Option<u64>,
    pub function_name_id: Option<u64>,
    pub mapping_id: Option<u64>,
    pub rel_pc: Option<u64>,
    pub source_path_iid: Option<u64>,
    pub line_number: Option<u32>,
}

Fields

iid: Option<u64>

Interning key. Starts from 1, 0 is the same as “not set”.

function_name_id: Option<u64>

E.g. “fopen” id of string.

mapping_id: Option<u64>

The mapping in which this frame’s instruction pointer resides. iid of Mapping.iid.

If set (non-zero), rel_pc MUST also be set. If mapping_id is 0 (not set), this frame has no associated memory mapping (e.g., symbolized frames without address information).

Starts from 1, 0 is the same as “not set”.

rel_pc: Option<u64>

Instruction pointer relative to the start of the mapping. MUST be set if mapping_id is set (non-zero). Ignored if mapping_id is 0.

source_path_iid: Option<u64>

Source file path for this frame. This is typically set during online symbolization when symbol information is available at trace collection time. If not set, source file paths may be added later via offline symbolization (see ModuleSymbols).

Starts from 1, 0 is the same as “not set”.

iid of InternedData.source_paths.

line_number: Option<u32>

Line number in the source file for this frame. This is typically set during online symbolization when symbol information is available at trace collection time. If not set, line numbers may be added later via offline symbolization (see ModuleSymbols).

Implementations

impl Frame

pub fn iid(&self) -> u64

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

pub fn function_name_id(&self) -> u64

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

pub fn mapping_id(&self) -> u64

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

pub fn rel_pc(&self) -> u64

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

pub fn source_path_iid(&self) -> u64

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

pub fn line_number(&self) -> u32

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

Trait Implementations

impl Clone for Frame

fn clone(&self) -> Frame

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Frame

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

Formats the value using the given formatter.

impl Default for Frame

fn default() -> Self

Returns the “default value” for a type.

impl Message for Frame

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 Frame

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