Struct Variant

#[non_exhaustive]
#[repr(C)]
pub struct Variant {
    pub name: &'static str,
    pub discriminant: Option<i64>,
    pub kind: VariantKind,
    pub offset: usize,
    pub doc: &'static [&'static str],
}

Describes a variant of an enum

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: &'static str

Name of the variant

discriminant: Option<i64>

Discriminant value (if available)

kind: VariantKind

Kind of variant (unit, tuple, or struct)

offset: usize

Offset of the variant in the enum layout

doc: &'static [&'static str]

Doc comment for the variant

Implementations

impl Variant

pub const fn builder() -> VariantBuilder

Returns a builder for Variant

Trait Implementations

impl Clone for Variant

fn clone(&self) -> Variant

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Variant

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

Formats the value using the given formatter.

impl Hash for Variant

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Variant

fn eq(&self, other: &Variant) -> 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.
