Struct ic_cdk::api::call::ManualReply

source · [−]

pub struct ManualReply<T: ?Sized>(_);

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

source

impl<T: ?Sized> ManualReply<T>

source

pub const fn empty() -> Self

Constructs a new ManualReply.

source

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

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

source

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

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