Struct HostContractStamp 

pub struct HostContractStamp {
    pub features: Vec<String>,
    pub min_host: Option<HostVersion>,
}

The host_contract block written into manifest.json at build time.

Deliberately tolerant: a newer toolchain may add stamp members or write a min_host this host cannot parse, and neither may turn a “this Node is too old” answer into “the package is broken”. Unknown members are ignored and an unparseable min_host reads as absent.

Fields

features: Vec<String>

Feature ids, sorted by id. Kept as strings so ids from newer toolchains survive parsing.

min_host: Option<HostVersion>
