Crate tank

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.
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 table column.
Context
ContextUpdater
CreateTableQueryBuilder
DeclareTableRef: Wrapper used when declaring table references in generated macros.
DropTableQueryBuilder
FixedDecimal: Decimal wrapper enforcing compile-time width/scale.
GenericSqlWriter: Fallback generic SQL writer (closest to PostgreSQL / DuckDB conventions).
InsertIntoQueryBuilder
Interval: A time interval supporting months, days and nanoseconds.
Join: Binary join with optional ON predicate.
NA
Ordered
QueryBuilder
QueryMetadata
RawQuery
References: Foreign key reference to another Entity’s columns.
RowLabeled: Row with column labels.
RowsAffected: Metadata about modifying operations (INSERT/UPDATE/DELETE).
SelectQueryBuilder
TableRef: Schema-qualified table reference (optional alias).
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: Polymorphic iterator adapter returning items from either variant.
Fragment
IntervalUnit: Units used to represent different parts of an Interval value.
JoinType: SQL join variants.
Operand
Order
Passive: Wrapper marking whether a column should be considered set or skipped (passive) on INSERT.
PrimaryKeyType: Indicates if and how a column participates in the primary key.
Query: Executable query: raw SQL or prepared statement.
QueryResult: Items from Executor::run: rows or effects.
QueryType
UnaryOpType
Value: SQL value representation used across Tank.

AsQuery
AsValue: Convert both ways between Rust types and Value (plus simple parsing).
ColumnTrait: Helper trait for types that expose an underlying 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 SQL dialect provider.
DropTableQuery
Entity: A table-mapped record with schema and CRUD helpers.
ErrorContext: Provides the context method for Result.
Executor: Async query executor bound to a concrete Driver.
Expression: Renderable SQL expression.
ExpressionCollection
OpPrecedence: Provides numeric precedence for expressions allowing sql writers to insert parentheses.
Prepared: A parameterized, backend-prepared query handle.
SelectQuery
SqlWriter: Dialect printer converting semantic constructs into concrete SQL strings.
Transaction: Transactional Executor with commit and rollback.

as_c_string: Convenience wrapper converting into a CString.
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.
print_date
print_timer
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
