Version

Struct Version 

Source
pub struct Version {
    pub language: Language,
    pub requires: BTreeSet<String>,
    pub source: String,
}
Expand description

One immutable version: the content a digest names.

Fields§

§language: Language

Its language.

§requires: BTreeSet<String>

The capability it declares it needs, its language’s included.

§source: String

The source text.

Implementations§

Source§

impl Version

Source

pub fn canonical(&self) -> Vec<u8> ⓘ

The bytes the digest is taken over:

ikigai-script/1\n
language <language>\n
requires <scope>\n        (one line per scope, sorted)
\n
<source>

A scope contains no whitespace and the source comes last, so the framing is unambiguous without escaping anything.

Source

pub fn digest(&self) -> String

The version’s name: sha256: and 64 lowercase hex digits over canonical.

use ikigai_script::model::{Language, Version};
let v = Version {
    language: Language::Lisp,
    requires: ["urn:cap:lisp".to_string()].into_iter().collect(),
    source: "(+ 1 2)".to_string(),
};
let digest = v.digest();
assert!(digest.starts_with("sha256:"));
assert_eq!(digest.len(), "sha256:".len() + 64);
assert!(digest["sha256:".len()..].bytes().all(|b| b.is_ascii_hexdigit() && !b.is_ascii_uppercase()));
// Content-addressed: the same content is the same version.
assert_eq!(digest, v.clone().digest());
Source

pub fn document(&self, name: &str) -> VersionDocument

The JSON face of this version under name.
