Struct SchemaObject 

pub struct SchemaObject {
    pub kind: String,
    pub name: String,
    pub table: String,
    pub root: u32,
    pub sql: String,
}

One row of sqlite_schema.

Fields

kind: String

table, index, view or trigger.

name: String

The object’s name.

table: String

The table the object belongs to; for a table, its own name.

root: u32

The root page, or 0 for an object with no b-tree.

sql: String

The CREATE statement the object was declared with.

Implementations

impl SchemaObject

pub fn column_names(&self) -> DbResult<Vec<String>>

Returns the column names the CREATE TABLE statement declares.

A deliberately small parser: it takes the text between the outermost parentheses, splits on commas that are not inside parentheses, and reads the first identifier of each part. That is enough for the fixtures and for the tables inillucent-migrate has to read, and it refuses rather than guesses on anything it does not recognise - a table constraint (PRIMARY KEY (...), UNIQUE (...), FOREIGN KEY, CHECK) is skipped rather than mistaken for a column.

A general answer needs the real parser in inillucent-sql, and this crate deliberately sits below it so that a migration tool does not drag the front end in. Phase 4 revisits this when DDL import needs types and constraints as well as names.
