Struct ManualReply

pub struct ManualReply<T: ?Sized>(/* private fields */);

👎Deprecated since 0.18.0: Please use std::marker::PhantomData with manual_reply instead.

Expand description

Pretends to have the Candid type T, but unconditionally errors when serialized.

Usable, but not required, as metadata when using #[query(manual_reply = true)], so an accurate Candid file can still be generated.

Implementations§

impl<T: ?Sized> ManualReply<T>

pub const fn empty() -> Self

👎Deprecated since 0.18.0: The api::call module is deprecated. Individual items within this module have their own deprecation notices with specific migration guidance.

Constructs a new ManualReply.

pub fn all<U>(value: U) -> Self
where U: ArgumentEncoder,

👎Deprecated since 0.18.0: The api::call module is deprecated. Individual items within this module have their own deprecation notices with specific migration guidance.

Replies with the given value and returns a new ManualReply, for a useful reply-then-return shortcut.

pub fn one<U>(value: U) -> Self
where U: CandidType,

👎Deprecated since 0.18.0: The api::call module is deprecated. Individual items within this module have their own deprecation notices with specific migration guidance.

Replies with a one-element tuple around the given value and returns a new ManualReply, for a useful reply-then-return shortcut.

pub fn reject(message: impl AsRef<str>) -> Self

👎Deprecated since 0.18.0: The api::call module is deprecated. Individual items within this module have their own deprecation notices with specific migration guidance.

Rejects the call with the specified message and returns a new ManualReply, for a useful reply-then-return shortcut.
