Struct Mapping 

#[repr(C)]
pub struct Mapping {
    pub id: Record<u64, 1, NO_OPT_ZERO>,
    pub memory_start: Record<u64, 2, OPT_ZERO>,
    pub memory_limit: Record<u64, 3, OPT_ZERO>,
    pub file_offset: Record<u64, 4, OPT_ZERO>,
    pub filename: Record<StringOffset, 5, OPT_ZERO>,
    pub build_id: Record<StringOffset, 6, OPT_ZERO>,
}

Represents a mapping in a profile. The boolean fields have been omitted to save bytes/CPU since they are unused in Datadog.

Fields

id: Record<u64, 1, NO_OPT_ZERO>

Unique nonzero id for the mapping.

memory_start: Record<u64, 2, OPT_ZERO>

Address at which the binary (or DLL) is loaded into memory.

memory_limit: Record<u64, 3, OPT_ZERO>

The limit of the address range occupied by this mapping.

file_offset: Record<u64, 4, OPT_ZERO>

Offset in the binary that corresponds to the first mapped address.

filename: Record<StringOffset, 5, OPT_ZERO>

The object this entry is loaded from. This can be a filename on disk for the main binary and shared libraries or virtual abstractions like “[vdso]”.

build_id: Record<StringOffset, 6, OPT_ZERO>

A string that uniquely identifies a particular program version with high probability. E.g., for binaries generated by GNU tools, it could be the contents of the .note.gnu.build-id field.

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() -> Mapping

Returns the “default value” for a type.

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.

impl Value for Mapping

Safety

The Default implementation will return all zero-representations.

const WIRE_TYPE: WireType = WireType::LengthDelimited

The wire type this value uses.

fn proto_len(&self) -> u64

The number of bytes it takes to encode this value. Do not include the number of bytes it takes to encode the length-prefix as a varint. For example, using this snippet of the reference:

fn encode<W: Write>(&self, writer: &mut W) -> Result<()>

Encode the value to the in-wire protobuf format. For length-delimited types, do not include the length-prefix; see Value::proto_len for more details.
