A symbol table entry in an Object.

This trait is part of the unified read API.

Required Methods

fn index(&self) -> SymbolIndex

The index of the symbol.

fn name_bytes(&self) -> Result<&'data [u8]>

The name of the symbol.

fn name(&self) -> Result<&'data str>

The name of the symbol.

Returns an error if the name is not UTF-8.

fn address(&self) -> u64

The address of the symbol. May be zero if the address is unknown.

fn size(&self) -> u64

The size of the symbol. May be zero if the size is unknown.

fn kind(&self) -> SymbolKind

Return the kind of this symbol.

fn section(&self) -> SymbolSection

Returns the section where the symbol is defined.

fn is_undefined(&self) -> bool

Return true if the symbol is undefined.

fn is_definition(&self) -> bool

Return true if the symbol is a definition of a function or data object that has a known address.

This is primarily used to implement Object::symbol_map.

fn is_common(&self) -> bool

Return true if the symbol is common data.

Note: does not check for SymbolSection::Section with SectionKind::Common.

fn is_weak(&self) -> bool

Return true if the symbol is weak.

fn scope(&self) -> SymbolScope

Returns the symbol scope.

fn is_global(&self) -> bool

Return true if the symbol visible outside of the compilation unit.

This treats SymbolScope::Unknown as global.

fn is_local(&self) -> bool

Return true if the symbol is only visible within the compilation unit.

fn flags(&self) -> SymbolFlags<SectionIndex, SymbolIndex>

Symbol flags that are specific to each file format.

Provided Methods

fn section_index(&self) -> Option<SectionIndex>

Returns the section index for the section containing this symbol.

May return None if the symbol is not defined in a section.
