Struct VariantFieldSpec 

pub struct VariantFieldSpec<'a> {
    pub name: Option<&'a str>,
    pub type_name: &'a str,
    pub size: usize,
    pub align: usize,
}

Description of a single payload field of a data-carrying enum variant.

Note the deliberate absence of an offset: Rust exposes no const way to read the byte offset of a field within an enum variant (offset_of! covers structs only). Rather than record a number it cannot verify — which would break the manifest’s “computed by the compiler, cannot drift” guarantee — ix records only what it can prove: the field’s name, spelled type, size and alignment.

Fields

name: Option<&'a str>

Field name for a struct-like variant; None for a tuple position.

type_name: &'a str

Spelled type, e.g. "u32".

size: usize

size_of of the field type.

align: usize

align_of of the field type.

Trait Implementations

impl<'a> Clone for VariantFieldSpec<'a>

fn clone(&self) -> VariantFieldSpec<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for VariantFieldSpec<'a>

impl<'a> Debug for VariantFieldSpec<'a>

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

Formats the value using the given formatter.

impl<'a> Eq for VariantFieldSpec<'a>

impl<'a> PartialEq for VariantFieldSpec<'a>

fn eq(&self, other: &VariantFieldSpec<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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