Struct Contract 

pub struct Contract {
    pub inputs: Arc<PortTable>,
    pub outputs: Arc<PortTable>,
    pub input_types: Vec<u64>,
    pub output_types: Vec<u64>,
    pub required_side_packets: Vec<String>,
    /* private fields */
}

A kernel’s port contract: payload-type constraints plus required side packets.

Port counts and names come from YAML and are already known when the contract is built; the kernel only fills in the types.

Fields

inputs: Arc<PortTable>

outputs: Arc<PortTable>

input_types: Vec<u64>

0 = 未声明(接受任意类型)

output_types: Vec<u64>

required_side_packets: Vec<String>

Implementations

impl Contract

pub fn new(inputs: Arc<PortTable>, outputs: Arc<PortTable>) -> Self

Trait Implementations
