Struct WorldManifest 

pub struct WorldManifest {
    pub component_counts: Vec<(u8, u32)>,
    pub max_blob_index: u32,
}

A verified summary of the blob’s shape, produced by cook from the final record streams and carried alongside them in the metadata block. The runtime trusts it (debug builds re-derive and assert it matches): the per-type counts pre-size the ECS columns before the bulk component load, and max_blob_index names the overflow files without scanning either stream. Anything further (type presence, feature flags) is deliberately not duplicated here: it is a counts lookup away.

Fields

component_counts: Vec<(u8, u32)>

(component discriminant, record count), ascending, nonzero counts only.

max_blob_index: u32

Highest blob index any payload locator references; 0 = no overflow.

Implementations

impl WorldManifest

pub fn from_records( defs: &[BlobAssetDef], resources: &[ResourceRecord], ) -> WorldManifest

Derive the manifest from the final record streams. Cook builds the shipped manifest with this (so it is consistent by construction); the runtime re-derives it in debug builds to assert the shipped copy matches.
