Struct DeclaredEndpoint 

pub struct DeclaredEndpoint {
    pub type_name: &'static str,
    pub topic: &'static str,
    pub depth: Option<u32>,
    pub reliability: Option<QoSReliabilityPolicy>,
    pub durability: Option<QoSDurabilityPolicy>,
}

One subscription this image’s contract declares something about.

Each column is None where nobody stated it – a row exists when ANY of the three is stated, so any one of them may be silent. type_name appears once in the ROS spelling and once DDS-mangled, as two rows, because which one a generated message class carries is a property of the codegen that produced it.

Fields

type_name: &'static str

topic: &'static str

depth: Option<u32>

The declared KEEP_LAST depth.

reliability: Option<QoSReliabilityPolicy>

Reliable / BestEffort – never SystemDefault, which says “the middleware chooses” and so cannot be disagreed with.

durability: Option<QoSDurabilityPolicy>

Volatile / TransientLocal, on the same rule.
