Struct DataSec

pub struct DataSec<'btf> { /* private fields */ }

An ELF’s data section, such as .data, .bss or .rodata.

Implementations

impl<'btf> DataSec<'btf>

pub fn is_empty(&self) -> bool

Whether this type has no members

pub fn len(&self) -> usize

How many members this DataSec has

pub fn get(&self, index: usize) -> Option<VarSecInfo>

Get a VarSecInfo at a given index

Errors

This function returns None when the index is out of bounds.

pub fn iter(&'btf self) -> impl ExactSizeIterator<Item = VarSecInfo> + 'btf

Returns an iterator over the VarSecInfo’s of the DataSec

Methods from Deref<Target = BtfType<'btf>>

pub fn type_id(&self) -> TypeId

This type’s type id.

pub fn name(&self) -> Option<&'btf OsStr>

This type’s name.

pub fn kind(&self) -> BtfKind

This type’s kind.

pub fn is_mod(&self) -> bool

Whether this represent’s a modifier.

pub fn is_any_enum(&self) -> bool

Whether this represents any kind of enum.

pub fn is_core_compat(&self, other: &Self) -> bool

Whether this btf type is core compatible to other.

pub fn is_composite(&self) -> bool

Whether this type represents a composite type (struct/union).

pub fn next_type(&self) -> Option<Self>

If this type implements ReferencesType, returns the type it references.

pub fn skip_mods_and_typedefs(&self) -> Self

Given a type, follows the refering type ids until it finds a type that isn’t a modifier or a BtfKind::Typedef.

See is_mod.

pub fn alignment(&self) -> Result<NonZeroUsize>

Returns the alignment of this type, if this type points to some modifier or typedef, those will be skipped until the underlying type (with an alignment) is found.

See skip_mods_and_typedefs.
