Struct symbolic::common::Name

pub struct Name<'a> { /* private fields */ }

The name of a potentially mangled symbol.

Debugging information often only contains mangled names in their symbol and debug information data. The mangling schema depends on the compiler and programming language. Name is a wrapper type for potentially mangled names and an optionally declared language. To demangle the name, see the demangle feature of symbolic.

Not all sources declare a programming language. In such a case, the language will be Unknown. However, it may still be inferred for demangling by inspecting the mangled string.

Names can refer either functions, types, fields, or virtual constructs. Their semantics are fully defined by the language and the compiler.

Examples

Create a name and print it:

use symbolic_common::Name;

let name = Name::from("_ZN3foo3barEv");
assert_eq!(name.to_string(), "_ZN3foo3barEv");

Create a name with a language and explicit mangling state. Alternate formatting prints the language:

use symbolic_common::{Language, Name, NameMangling};

let name = Name::new("_ZN3foo3barEv", NameMangling::Mangled, Language::Cpp);
assert_eq!(format!("{:#}", name), "_ZN3foo3barEv [C++]");

Implementations

impl<'a> Name<'a>

pub fn new<S>(string: S, mangling: NameMangling, lang: Language) -> Name<'a> where
    S: Into<Cow<'a, str>>, 

Constructs a new Name with given mangling and language.

In case both the mangling state and the language are unknown, a simpler alternative to use is Name::from.

Example

use symbolic_common::{Language, Name, NameMangling};

let name = Name::new("_ZN3foo3barEv", NameMangling::Mangled, Language::Cpp);
assert_eq!(format!("{:#}", name), "_ZN3foo3barEv [C++]");

pub fn as_str(&self) -> &str

Returns the raw, mangled string of the name.

Example

use symbolic_common::{Language, Name, NameMangling};

let name = Name::new("_ZN3foo3barEv", NameMangling::Mangled, Language::Cpp);
assert_eq!(name.as_str(), "_ZN3foo3barEv");

This is also available as an AsRef<str> implementation:

use symbolic_common::{Language, Name, NameMangling};

let name = Name::new("_ZN3foo3barEv", NameMangling::Mangled, Language::Cpp);
assert_eq!(name.as_ref(), "_ZN3foo3barEv");

pub fn set_language(&mut self, language: Language) -> &mut Name<'a>

Set the Name’s language.

pub fn language(&self) -> Language

The language of the mangled symbol.

If the language is not declared in the source, this returns Language::Unknown. The language may still be inferred using detect_language, which is declared on the Demangle extension trait.

Example

use symbolic_common::{Language, Name, NameMangling};

let name = Name::new("_ZN3foo3barEv", NameMangling::Mangled, Language::Cpp);
assert_eq!(name.language(), Language::Cpp);

pub fn set_mangling(&mut self, mangling: NameMangling) -> &mut Name<'a>

Set the Name’s mangling state.

pub fn mangling(&self) -> NameMangling

Returns the Name’s mangling state.

Example

use symbolic_common::{Language, Name, NameMangling};

let unmangled = Name::new("foo::bar", NameMangling::Unmangled, Language::Unknown);
assert_eq!(unmangled.mangling(), NameMangling::Unmangled);

pub fn into_cow(self) -> Cow<'a, str>

Converts this name into a Cow.

Example

use symbolic_common::Name;

let name = Name::from("_ZN3foo3barEv");
assert_eq!(name.into_cow(), "_ZN3foo3barEv");

pub fn into_string(self) -> String

Converts this name into a String.

Example

use symbolic_common::Name;

let name = Name::from("_ZN3foo3barEv");
assert_eq!(name.into_string(), "_ZN3foo3barEv");
