Macro mpstthree::offer_mpst

macro_rules! offer_mpst {
    ($session : expr, $recv_mpst : ident, { $($pat : pat => $result : expr,) + }) => { ... };
    ($session : expr, { $($pat : pat => $result : expr,) + }) => { ... };
}

This is supported on crate feature macros_multiple only.

Offer a choice between many different sessions wrapped in an enum

Arguments

• The session to be used
• [Optional] The recv function that will be used
• Each path, which are each variant of the enum which contains the new branches
• The block of code to process each new session

Basic example

offer_mpst!(
    s,
    recv_mpst_a_from_d,
    {
        CBranchesAtoC::End(s) => {
            close_mpst_multi(s)
        },
        CBranchesAtoC::Video(s) => {
            let (request, s) = recv_mpst_a_from_d(s)?;
            let s = send_mpst_a_to_b(request + 1, s);
            let (video, s) = recv_mpst_a_from_b(s)?;
            let s = send_mpst_a_to_d(video + 1, s);
            authenticator_recurs(s)
        },
    }
)?;

Baking example

offer_mpst!(
    s,
    {
        CBranchesAtoC::End(s) => {
            close_mpst_multi(s)
        },
        CBranchesAtoC::Video(s) => {
            let (request, s) = recv_mpst_a_from_d(s)?;
            let s = send_mpst_a_to_b(request + 1, s);
            let (video, s) = recv_mpst_a_from_b(s)?;
            let s = send_mpst_a_to_d(video + 1, s);
            authenticator_recurs(s)
        },
    }
)?;

This macro is available only if MultiCrusty is built with the "macros_multiple" feature.
