Struct PokeStruct 

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

Lets you mutate a struct’s fields.

Implementations

impl<'mem, 'facet> PokeStruct<'mem, 'facet>

pub fn ty(&self) -> &StructType

Returns the struct definition.

pub fn field_count(&self) -> usize

Returns the number of fields in this struct.

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

Returns a Poke for the field at the given index.

This always succeeds (for valid indices). The POD check happens when you try to mutate via Poke::set on the returned field poke, or when calling PokeStruct::set_field which checks the parent struct.

pub fn field_by_name( &mut self, name: &str, ) -> Result<Poke<'_, 'facet>, ReflectError>

Returns a Poke for the field with the given name.

Returns an error if the field is not found.

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

Sets the value of a field by index.

The value type must match the field’s type.

Returns an error if the parent struct is not POD. Field mutation could violate struct-level invariants, so the struct must be marked with #[facet(pod)] to allow this.

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

Sets the value of a field by name.

The value type must match the field’s type.

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

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

pub fn peek_field_by_name( &self, name: &str, ) -> Result<Peek<'_, 'facet>, FieldError>

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_struct(&self) -> PeekStruct<'_, 'facet>

Returns a read-only PeekStruct view.

Trait Implementations

impl Debug for PokeStruct<'_, '_>

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

Formats the value using the given formatter.
