Modules§

cols: Build a slice of column expressions (optionally ordered) suitable for a SELECT projection. Each comma separated item becomes either an expression (parsed via expr!) or an ordered expression when followed by ASC or DESC.
current_timestamp_ms
expr: Parse a Rust expression into a typed SQL expression tree.
impl_executor_transaction: Implement the Executor trait for a transaction wrapper type by delegating each operation to an underlying connection object.
join: Build a typed join tree from a concise SQL-like syntax.
month_to_number
number_to_month
possibly_parenthesized: Conditionally wrap a generated fragment in parentheses.
send_value: Sends the value through the channel and logs in case of error.
truncate_long: Truncate long strings for logging and error messages purpose.

BinaryOp
ColumnDef: Column specification.
ColumnRef: Reference to a column.
Context: Holds state during SQL generation, including current fragment, table context, and formatting options.
ContextUpdater
CreateTableQueryBuilder
DeclareTableRef: Wrapper used when declaring table references in generated macros.
DropTableQueryBuilder
FindOrder
FixedDecimal: Decimal wrapper enforcing static precision/scale.
GenericSqlWriter: Generic SQL writer.
InsertIntoQueryBuilder
Interval: Calendar-aware time interval.
IsAggregateFunction
IsAlias
IsAsterisk
IsConstant
IsFalse
IsQuestionMark
IsTrue
Join: Binary join with optional ON predicate.
NA
Ordered
QueryBuilder
RawQuery
References: Represents a foreign key constraint to another entity.
Row: Row with column labels.
RowsAffected: Result of a modifying operation (INSERT/UPDATE/DELETE).
SelectQueryBuilder
TableRef: Reference to a database table, including schema, alias name, columns, and primary key.
TypeDecoded: Internally decoded type info for macros.
UnaryOp

Action: Referential action for foreign key updates or deletes.
BinaryOpType
DefaultValueType
DynQuery: Dyn compatible version of Query
EitherIterator: Iterator adapter for two types.
Fragment: Represents the context or part of the SQL statement currently being generated.
IntervalUnit: Time interval units.
JoinType: SQL join type variants.
Operand
Order
Passive: Value wrapper for optional persistence.
PrimaryKeyType: Primary key participation.
Query: Executable query: raw SQL or prepared statement.
QueryResult: Items from Executor::run: rows or effects.
UnaryOpType
Value: SQL value representation.

AsQuery
AsValue: Bidirectional conversion between Rust types and Value.
ColumnTrait: Trait exposing column definition and reference.
Connection: A live database handle capable of executing queries and spawning transactions.
CreateTableQuery
Dataset: Queryable data source (table or join tree).
Driver: Backend connector and dialect.
DropTableQuery
Entity: Database entity mapping.
ErrorContext: Provides the context method for Result.
Executor: Async query execution.
Expression: Renderable SQL expression.
ExpressionCollection
ExpressionVisitor
OpPrecedence: Provides numeric precedence for expressions allowing sql writers to insert parentheses.
Prepared: Parameterized, backend-prepared query handle.
SelectQuery: SELECT query builder.
SqlWriter: SQL dialect printer.
Transaction: Transactional Executor with commit and rollback.

as_c_string: Convenience wrapper converting into a CString.
column_def
consume_while: Consume a prefix of input while the predicate returns true, returning that slice.
error_message_from_ptr
extract_number
matches_path: Determine if the trailing segments of a syn::Path match the expected identifiers.
quote_btree_map: Quote a BTreeMap<K, V> into tokens.
quote_cow: Quote a Cow<T> preserving borrowed vs owned status for generated code.
quote_option: Quote an Option<T> into tokens.
separated_by: Write an iterator of items separated by a delimiter into a string.
value_to_json
write_escaped: Write, escaping occurrences of search char with replace while copying into buffer.
