Desc

Enum Desc 

Source
pub enum Desc {
    Js {
        name: &'static str,
        transfer: bool,
    },
    Postcard(&'static NamedType),
    Inline(&'static NamedType),
    Option(&'static Desc),
    Result(&'static Desc, &'static Desc),
}
Expand description

How one value crosses the channel.

This mirrors [crate::codec::WireArg]: the Option and Result variants describe the wrapper structure that the macro walks, and the leaves say whether the value travels as a Javascript value or as postcard bytes.

Variants§

§

Js

Fields

§name: &'static str

The DOM class name of the wrapped type, from JsName.

§transfer: bool

Whether the value goes on the transfer list.

§

Postcard(&'static NamedType)

A postcard-encoded leaf.

§

Inline(&'static NamedType)

A &str or &[u8] argument, written into the request payload directly with no WireArg around it.

§

Option(&'static Desc)

Option<T>, whose Some and None route independently.

§

Result(&'static Desc, &'static Desc)

Result<T, E>, whose Ok and Err route independently.
