Struct PokeTuple 

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

Lets you mutate a tuple’s fields (by index).

Tuples are just tuple-struct types without names, so this is a thin wrapper that exposes ordered field access.

Implementations

impl<'mem, 'facet> PokeTuple<'mem, 'facet>

pub const fn len(&self) -> usize

Returns the number of fields in this tuple.

pub const fn is_empty(&self) -> bool

Returns true if this tuple has no fields.

pub const fn ty(&self) -> TupleType

Tuple type information.

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

Returns a read-only Peek for the field at the given index.

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

Returns a mutable Poke for the field at the given index.

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

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

Converts this back into the underlying Poke.

pub fn as_peek_tuple(&self) -> PeekTuple<'_, 'facet>

Returns a read-only PeekTuple view.

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

Formats the value using the given formatter.
