A single variant of an enumeration.

Variants

Struct

A struct-like variant that is composed of a list of fields.

Fields

format: Format

The formatter setting for this variant.

source_field: Option<FieldRef>

The field to be used as the source of the error.

variant_name: Ident

The name of the current variant.

field_list: FieldList

The field list of this struct-like variant.

Unit

An unit variant that has no fields.

Fields

format: Format

The formatter setting for this variant.

variant_name: Ident

The name of the current variant.

Transparent

A transparent variant that is transparent over some downstream type.s

Fields

transparent: Transparent

The transparence setting for this variant.

variant_name: Ident

The name of the current variant.

field_list: FieldList

The field list of this struct-like variant.

Forward

A forward variant that forwards to one of its fields.

Fields

format: Format

The formatter setting for this variant.

variant_name: Ident

The name of the current variant.

field_ref: FieldRef

The forwarded field.

field_type: Type

The type of the forwarded field.

Trait Implementations

impl Clone for Variant

fn clone(&self) -> Variant

Returns a duplicate 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.
