Available on crate feature macros_multiple only.

Creates a send function to send from a given binary session type of a MeshedChannels with more than 3 participants. Checks if the first binary session has a “cancel” signal and panic if yes. The send function will try to send and panic if not possible (canceled session).

Arguments

• The name of the new send function
• The name of the receiver
• The name of the sender
• The name of the MeshedChannels type that will be used
• The number of participants (all together)
• The index of the binary session type that will receive in the MeshedChannels for this specific role. Index starts at 2 as 1 is an End.

Example

use mpstthree::{
    create_meshedchannels, create_normal_name, create_normal_role, create_send_check_cancel,
};

create_normal_role!(RoleB, RoleBDual);
create_normal_role!(RoleD, RoleDDual);

create_normal_name!(NameD);

create_meshedchannels!(MeshedChannels, 3);

create_send_check_cancel!(send_cancel_d_to_b, RoleB, NameD, MeshedChannels, 3, 2);

Compile fail

use mpstthree::{create_meshedchannels, create_normal_name, create_normal_role, create_send_check_cancel};

create_normal_role!(RoleA, RoleADual);
create_normal_role!(RoleD, RoleDDual);

create_normal_name!(NameD);

create_meshedchannels!(MeshedChannels, 3);

create_send_check_cancel!(send_cancel_d_to_b, RoleA, NameD, MeshedChannels, 3, 1);
