Struct PokeResult 

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

Lets you mutate a result (implements mutable result operations)

Implementations

impl<'mem, 'facet> PokeResult<'mem, 'facet>

pub const unsafe fn new(value: Poke<'mem, 'facet>, def: ResultDef) -> Self

Creates a new poke result

Safety

The caller must ensure that def contains valid vtable function pointers that correctly implement the result operations for the actual type, and that the ok/err types match def.t() / def.e().

pub const fn def(&self) -> ResultDef

Returns the result definition

pub const fn vtable(&self) -> &'static ResultVTable

Returns the result vtable

pub fn is_ok(&self) -> bool

Returns whether the result is Ok

pub fn is_err(&self) -> bool

Returns whether the result is Err

pub fn ok(&self) -> Option<Peek<'_, 'facet>>

Returns the Ok value as a read-only Peek if the result is Ok, None otherwise.

pub fn err(&self) -> Option<Peek<'_, 'facet>>

Returns the Err value as a read-only Peek if the result is Err, None otherwise.

pub fn ok_mut(&mut self) -> Option<Poke<'_, 'facet>>

Returns the Ok value as a mutable Poke if the result is Ok, None otherwise.

pub fn err_mut(&mut self) -> Option<Poke<'_, 'facet>>

Returns the Err value as a mutable Poke if the result is Err, None otherwise.

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

Sets the result to Ok(value), dropping the previous value.

pub fn set_err<E: Facet<'facet>>( &mut self, value: E, ) -> Result<(), ReflectError>

Sets the result to Err(value), dropping the previous value.

pub fn set_ok_from_heap<const BORROW: bool>( &mut self, value: HeapValue<'facet, BORROW>, ) -> Result<(), ReflectError>

Type-erased set_ok.

Accepts a HeapValue whose shape must match the result’s Ok type.

pub fn set_err_from_heap<const BORROW: bool>( &mut self, value: HeapValue<'facet, BORROW>, ) -> Result<(), ReflectError>

Type-erased set_err.

Accepts a HeapValue whose shape must match the result’s Err type.

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

Converts this PokeResult back into a Poke

pub fn as_peek_result(&self) -> PeekResult<'_, 'facet>

Returns a read-only PeekResult view
