Module sqlite_loadable::table

Defining virtual tables and table functions on sqlite3 database connections.

Structs

• Constraint
  Wraps the raw sqlite3_index_constraint and sqlite3_index_constraint_usage C structs for ergonomic use in Rust.
• InValues
• IndexInfo
  Wraps the raw sqlite3_index_info C struct, which represents the possible constraints and outputs the xBestIndex method should use and return. https://www.sqlite.org/c3ref/index_info.html
• OrderBy
• VTabArguments
  Represents all the arguments given to the virtual table implementation during xCreate, from the underlying argv/argc strings. Parsed to be more easily readable.

Enums

• BestIndexError
  Possible errors to return in xBestIndex.
• ConstraintOperator
  Possible operators for a given constraint, found and used in xBestIndex and xFilter. https://www.sqlite.org/c3ref/c_index_constraint_eq.html TODO EQ=Equals, GT=GreaterThan, etc.
• OrderByDirection
• UpdateOperation

Traits

• VTab
• VTabCursor
• VTabFind
• VTabWriteable
• VTabWriteableNestedTransactions
• VTabWriteableWithTransactions

Functions

• define_table_function
  Define a table function on the given sqlite3 database. “Table function” is the same as “eponymous-only” virtual table described at https://www.sqlite.org/vtab.html#eponymous_only_virtual_tables
• define_table_function_with_find
• define_virtual_table
  Define a virtual table on the sqlite3 database connection. Optionally pass in an auxillary object, which
• define_virtual_table_with_find
• define_virtual_table_writeable
• define_virtual_table_writeable_with_transactions
• define_virtual_table_writeablex
• operator
  Return the ConstraintOperator for the given raw operator, usually from sqlite3_index_info.sqlite3_index_constraint.op . Values from https://www.sqlite.org/c3ref/c_index_constraint_eq.html
