Struct Constitution 

pub struct Constitution {
    pub engine_version: &'static str,
    pub formats: Vec<FormatVersion>,
    pub capabilities: Vec<&'static str>,
    pub invariants: Vec<Invariant>,
    pub grammar_digest: String,
}

Everything this engine guarantees, packaged for a client to verify against.

Fields

engine_version: &'static str

formats: Vec<FormatVersion>

capabilities: Vec<&'static str>

invariants: Vec<Invariant>

grammar_digest: String

Digest of the grammar THIS ENGINE implements. Never a digest of something the client supplied.

Implementations

impl Constitution

pub fn digest(&self) -> String

A stable digest of the whole Constitution.

Built from an explicit ordered encoding rather than from serialized JSON: every list here is a Vec walked in declaration order, no hash map is involved at any point, and the counts are committed so a truncated list cannot digest as a shorter one. Declaration order IS committed — the lists are append-only, so reordering them is a change to the artifact and should read as one.
