Struct PokeEnum 

pub struct PokeEnum<'mem, 'facet> { /* private fields */ }

Lets you mutate an enum’s fields.

Implementations

impl<'mem, 'facet> PokeEnum<'mem, 'facet>

pub fn ty(&self) -> EnumType

Returns the enum definition

pub fn enum_repr(&self) -> EnumRepr

Returns the enum representation

pub fn variants(&self) -> &'static [Variant]

Returns the enum variants

pub fn variant_count(&self) -> usize

Returns the number of variants in this enum

pub fn variant_name(&self, index: usize) -> Option<&'static str>

Returns the variant name at the given index

pub fn discriminant(&self) -> i64

Returns the discriminant value for the current enum value

Note: For RustNPO (null pointer optimization) types, there is no explicit discriminant stored in memory. In this case, 0 is returned. Use variant_index() to determine the active variant for NPO types.

pub fn variant_index(&self) -> Result<usize, VariantError>

Returns the variant index for this enum value

pub fn active_variant(&self) -> Result<&'static Variant, VariantError>

Returns the active variant

pub fn variant_name_active(&self) -> Result<&'static str, VariantError>

Returns the name of the active variant for this enum value

pub fn field( &mut self, index: usize, ) -> Result<Option<Poke<'_, 'facet>>, VariantError>

Returns a Poke handle to a field of a tuple or struct variant by index

pub fn field_index( &self, field_name: &str, ) -> Result<Option<usize>, VariantError>

Returns the index of a field in the active variant by name

pub fn field_by_name( &mut self, field_name: &str, ) -> Result<Option<Poke<'_, 'facet>>, VariantError>

Returns a Poke handle to a field of a tuple or struct variant by name

pub fn set_field<T: Facet<'facet>>( &mut self, index: usize, value: T, ) -> Result<(), ReflectError>

Sets a field of the current variant by index.

Returns an error if:

• The parent enum is not POD
• The index is out of bounds
• The value type doesn’t match the field type

pub fn set_field_by_name<T: Facet<'facet>>( &mut self, name: &str, value: T, ) -> Result<(), ReflectError>

Sets a field of the current variant by name.

Returns an error if:

• The parent enum is not POD
• No field with the given name exists
• The value type doesn’t match the field type

pub fn peek_field( &self, index: usize, ) -> Result<Option<Peek<'_, 'facet>>, VariantError>

Gets a read-only view of a field by index.

pub fn peek_field_by_name( &self, field_name: &str, ) -> Result<Option<Peek<'_, 'facet>>, VariantError>

Gets a read-only view of a field by name.

pub fn into_inner(self) -> Poke<'mem, 'facet>

Converts this back into the underlying Poke.

pub fn as_peek_enum(&self) -> PeekEnum<'_, 'facet>

Returns a read-only PeekEnum view.

Trait Implementations

impl Debug for PokeEnum<'_, '_>

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

Formats the value using the given formatter.
