Structs§

AtomicViewState: Atomic wrapper for #name
BTreeCharacteristics
BTreeTable
CheckConstraint
ColDef
Column
ColumnsMut
ForeignKey
FromClauseSubquery: A derived table from a FROM clause subquery.
FromClauseSubqueryCteMetadata
Index
IndexColumn
MakeFromBtreeState: State machine for async schema loading - passed by caller, not stored on Schema
PseudoCursorType
ResetOnClone: RAII wrapper that resets its inner value when cloned.
ResolvedFkRef: A single resolved foreign key where parent_table == target.
ResolvedType: Custom type definition, loaded from sqlite_turso_types A fully-resolved custom type: the chain of TypeDefs from the named type up to the ultimate primitive, plus the primitive name itself.
Schema
Sequence: Schema descriptor for a sequence. Pure data — the runtime state lives in the backing table __turso_internal_seq_<name> and is read from disk by Insn::SequenceComputeNext + surrounding cursor bytecode on every nextval/setval call. See core/translate/sequence.rs and the disk-only design notes above.
StructDef: Definition for a STRUCT composite type.
StructFieldDef: Field definition within a StructDef.
Trigger: Trigger structure
TypeDef
UnionDef: Definition for a UNION discriminated union type.
UnionVariantDef: Variant definition within a UnionDef.
UniqueSet
View: Simple view structure for non-materialized views

ColumnLayout: Maps schema column indices to register offsets for DML operations.
GeneratedType
MakeFromBtreePhase: Phase tracking for async schema loading
SchemaObjectType: Type of schema object for conflict checking
Table
Type
TypeDefKind: The kind-specific payload of a custom type.
ViewState

AUTOINCREMENT_SEQ_PREFIX
DBSP_TABLE_PREFIX
EXPR_INDEX_SENTINEL: The Position in Table for indexes which are arbitrary expressions (index.expr.is_some())
RESERVED_TABLE_PREFIXES: Internal table prefixes that should be protected from CREATE/DROP
ROWID_SENTINEL: Used to refer to the implicit rowid column in tables without an alias during UPDATE
SCHEMA_TABLE_NAME
SCHEMA_TABLE_NAME_ALT
SEQ_BACKING_TABLE_PREFIX
SQLITE_SEQUENCE_TABLE_NAME
TEMP_SCHEMA_TABLE_NAME
TEMP_SCHEMA_TABLE_NAME_ALT
TURSO_INTERNAL_PREFIX
TURSO_TYPES_TABLE_NAME

_build_pseudo_table
allow_user_dml
autoincrement_sequence_name: Name of the hidden sequence owned by an AUTOINCREMENT table.
collect_column_dependencies_of_expr: Extract all column name references from an expression as a set. columns is used to resolve pre-resolved Expr::Column { SELF_TABLE } back to names.
create_table
is_system_table: Check if a table name refers to a system table that should be protected from direct writes
render_gencol_expr_sql_with_new_names: Re-render the SQL text of a generated-column expression using current column names. The input AST may have been previously resolved into Expr::Column { table: SELF_TABLE, column: idx, .. } nodes; we replace each such self-table reference with a fresh Expr::Id(<col-name>) before stringifying so the result round-trips through the parser, even if a referenced column was renamed since the original original_sql was captured.
resolve_gencol_expr_columns: Resolve Expr::Id / Expr::Qualified / Expr::DoublyQualified in a generated column or partial-index expression to Expr::Column { table: SELF_TABLE, column: idx }.
rewrite_value_to_column: Recursively rewrite Expr::Id("value") (case-insensitive) to Expr::Id(col_name).
sqlite_schema_table
translate_ident_to_string_literal: SQLite treats bare identifiers in DEFAULT clauses as string literals. E.g., DEFAULT hello becomes the string “hello”, not a column reference.
