Struct Mapping 

pub struct Mapping {
    pub memory_start: u64,
    pub memory_limit: u64,
    pub file_offset: u64,
    pub filename: StringId,
    pub build_id: StringId,
}

Represents a [pprof::Mapping] with some space-saving changes:

• The id is not stored on the struct. It’s stored in the container that holds the struct.
• ids for linked objects use 32-bit numbers instead of 64 bit ones.

Fields

memory_start: u64

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

memory_limit: u64

The limit of the address range occupied by this mapping.

file_offset: u64

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

filename: StringId

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: StringId

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 Hash for Mapping

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Item for Mapping

type Id = MappingId

The Id associated with this Item, e.g. Function -> FunctionId.

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.
