Struct ColSpec 

pub struct ColSpec {
    pub name: &'static str,
    pub type_ddl: String,
    pub nullable: bool,
    pub default: Option<&'static str>,
    pub is_primary_key: bool,
}

Fields

name: &'static str

Compile-time constant — canonical chunkshop columns are always known at build time ("id", "doc_id", "embedding", etc.). Promoted- metadata columns flow through add_column_if_not_exists_sql, not through ColSpec, so this never needs to be runtime-derived.

type_ddl: String

Backend-specific. May be runtime-computed (e.g., format!("vector({dim})")), hence String rather than &'static str.

nullable: bool

default: Option<&'static str>

is_primary_key: bool
