Struct libbpf_rs::btf::types::Int

pub struct Int<'btf> {
    pub encoding: IntEncoding,
    pub offset: u8,
    pub bits: u8,
    /* private fields */
}

An integer.

Fields

encoding: IntEncoding

The encoding of the number.

offset: u8

The offset in bits where the value of this integer starts. Mostly usefull for bitfields in structs.

bits: u8

The number of bits in the int. (For example, an u8 has 8 bits).

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

pub fn type_id(&self) -> TypeId

This type’s type id.

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

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.
