Expand description

The possible types of sections that can be loaded from a crate object file.

Variants§

§

Text

A text section contains executable code, i.e., functions.

§

Rodata

An rodata section contains read-only data, i.e., constants.

§

Data

A data section contains data that is both readable and writable, i.e., static variables.

§

Bss

A bss section is just like a data section, but is automatically initialized to all zeroes at load time.

§

TlsData

A .tdata section is a read-only section that holds the initial data “image” for a thread-local storage (TLS) area.

§

TlsBss

A .tbss section is a read-only section that holds all-zero data for a thread-local storage (TLS) area. This is is effectively an empty placeholder: the all-zero data section doesn’t actually exist in memory.

§

Cls

A .cls section is a read-only section that holds the initial data “image” for a CPU-local (CLS) area.

§

GccExceptTable

A .gcc_except_table section contains landing pads for exception handling, comprising the LSDA (Language Specific Data Area), which is effectively used to determine when we should stop the stack unwinding process (e.g., “catching” an exception).

Mailing list discussion here: https://gcc.gnu.org/ml/gcc-help/2010-09/msg00116.html

Here is a sample repository parsing this section: https://github.com/nest-leonlee/gcc_except_table

§

EhFrame

The .eh_frame section contains information about stack unwinding and destructor functions that should be called when traversing up the stack for cleanup.

Implementations§

§

impl SectionType

pub const fn name(&self) -> &'static str

Returns the const &str name of this SectionType.

pub fn is_data_or_bss(&self) -> bool

Returns true if Data or Bss, otherwise false.

pub fn is_tls(&self) -> bool

Returns true if TlsData or TlsBss, otherwise false.

Trait Implementations§

§

impl Clone for SectionType

§

fn clone(&self) -> SectionType

Returns a copy of the value. Read more
1.0.0 · source§

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

§

impl Debug for SectionType

§

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

impl<'de> Deserialize<'de> for SectionType

§

§

impl PartialEq<SectionType> for SectionType

§

fn eq(&self, other: &SectionType) -> bool

1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
