Struct TableMeta 

pub struct TableMeta {
    pub name: String,
    pub ident: Ident,
    pub columns: Vec<ColumnMeta>,
    pub databases: Vec<String>,
    pub pkey: Option<String>,
}

Metadata used for IntoArguments, TableMeta, and (subset of) Model This structs are constructed from the *Attribute structs in crate::attr.

Fields

name: String

ident: Ident

columns: Vec<ColumnMeta>

databases: Vec<String>

pkey: Option<String>

If you’re using this, consider whether you should be using a ModelMetadata and its pkey, which is not optional, instead.
