Struct GeneratedBy 

pub struct GeneratedBy {
    pub generator: String,
    pub program: String,
    pub program_hash: String,
    pub seed: u64,
    pub region: [i32; 3],
    pub params: BTreeMap<String, i64>,
    pub roles: BTreeMap<String, String>,
}

Everything needed to reproduce the .nbt byte for byte (ADR-0006).

Every input that reaches the bytes, and nothing that does not. A record missing one of them is worse than no record: it names a set of inputs, and a re-expansion from that set produces a different artifact while the document claims byte reproducibility. The set is the source program, the overrides applied to it, the region and the seed.

Fields

generator: String

The back end that produced the bytes.

program: String

The source program’s name.

program_hash: String

sha256:<64 hex> over the canonical JSON of the program as expanded — the source document with Self::params and Self::roles already applied. It is therefore the checksum of the reproduction rather than a second statement of it: apply the overrides to the named document and this is the hash you must get.

seed: u64

The expansion seed.

region: [i32; 3]

The region the program was expanded over, [x, y, z]. An independent input: the same program at the same seed over a different box is a different building.

params: BTreeMap<String, i64>

Integer parameters overridden on the way in (delvec grammar expand --param), by name. Empty — and absent from the document — where the program was expanded as written.

roles: BTreeMap<String, String>

Palette roles rebound on the way in (--role), by name, each the block state as the caller wrote it. The axis frame is not recorded because it is not an input: a rebind inherits the frame of the binding it replaces, which the named source document already carries.

Trait Implementations

impl Clone for GeneratedBy

fn clone(&self) -> GeneratedBy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GeneratedBy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GeneratedBy

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for GeneratedBy

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for GeneratedBy

fn eq(&self, other: &GeneratedBy) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for GeneratedBy

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,
