Struct Symbol

pub struct Symbol {
    pub name: Option<Vec<u8>>,
    pub addr: Option<*mut c_void>,
    pub lineno: Option<u32>,
    pub filename: Option<PathBuf>,
}

Symbol is a representation of a function symbol. It contains name and addr of it. If built with debug message, it can also provide line number and filename. The name in it is not demangled.

Fields

name: Option<Vec<u8>>

This name is raw name of a symbol (which hasn’t been demangled).

addr: Option<*mut c_void>

The address of the function. It is not 100% trustworthy.

lineno: Option<u32>

Line number of this symbol. If compiled with debug message, you can get it.

filename: Option<PathBuf>

Filename of this symbol. If compiled with debug message, you can get it.

Implementations

impl Symbol

pub fn raw_name(&self) -> &[u8]

pub fn name(&self) -> String

pub fn sys_name(&self) -> Cow<'_, str>

pub fn filename(&self) -> Cow<'_, str>

pub fn lineno(&self) -> u32

Trait Implementations

impl Clone for Symbol

fn clone(&self) -> Symbol

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Symbol

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

Formats the value using the given formatter.

impl Display for Symbol

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

Formats the value using the given formatter.

impl<T> From<&T> for Symbol

where T: Symbol,

fn from(symbol: &T) -> Self

Converts to this type from the input type.

impl Hash for Symbol

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 PartialEq for Symbol

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