Struct ArenaParser 

pub struct ArenaParser<'arena> { /* private fields */ }

Arena-based SQL parser.

Unlike the standard Parser, this parser allocates all AST nodes from a bump arena, resulting in:

• O(1) allocation time (vs heap allocation overhead)
• Better cache locality (contiguous memory)
• Single deallocation when arena is dropped

Implementations

impl<'arena> ArenaParser<'arena>

pub fn parse_alter_table_statement( &mut self, ) -> Result<&'arena AlterTableStmt<'arena>, ParseError>

Parse ALTER TABLE statement.

impl<'arena> ArenaParser<'arena>

pub fn new_with_spans( tokens: Vec<Token>, spans: Vec<Span>, input: &'arena str, arena: &'arena Bump, ) -> Self

Create a new arena parser from tokens with spans and original input.

pub fn new(tokens: Vec<Token>, arena: &'arena Bump) -> Self

Create a new arena parser from tokens (legacy constructor without spans). Source text reconstruction will fall back to token-based reconstruction.

pub fn interner(&self) -> &ArenaInterner<'arena>

Returns a reference to the interner for symbol resolution during conversion.

pub fn into_interner(self) -> ArenaInterner<'arena>

Consumes the parser and returns the interner.

pub fn parse_sql( input: &str, arena: &'arena Bump, ) -> Result<Statement<'arena>, ParseError>

Parse SQL input string into an arena-allocated Statement.

Supports the full range of SQL statements including DML (SELECT, INSERT, UPDATE, DELETE), DDL (CREATE, DROP, ALTER), and transaction statements.

pub fn parse_select( input: &str, arena: &'arena Bump, ) -> Result<&'arena SelectStmt<'arena>, ParseError>

Parse SQL input string into an arena-allocated SelectStmt.

Convenience method for when you know you’re parsing a SELECT.

pub fn parse_select_with_interner( input: &str, arena: &'arena Bump, ) -> Result<(&'arena SelectStmt<'arena>, ArenaInterner<'arena>), ParseError>

Parse SQL input string into an arena-allocated SelectStmt, returning the interner too.

Use this method when you need to resolve Symbol values to strings.

pub fn parse_expression_sql( input: &str, arena: &'arena Bump, ) -> Result<&'arena Expression<'arena>, ParseError>

Parse an expression and return an arena-allocated reference.

pub fn parse_alter_table_sql( input: &str, arena: &'arena Bump, ) -> Result<&'arena AlterTableStmt<'arena>, ParseError>

Parse SQL input string into an arena-allocated AlterTableStmt.

pub fn parse_insert( input: &str, arena: &'arena Bump, ) -> Result<&'arena InsertStmt<'arena>, ParseError>

Parse an INSERT statement into an arena-allocated InsertStmt.

pub fn parse_update( input: &str, arena: &'arena Bump, ) -> Result<&'arena UpdateStmt<'arena>, ParseError>

Parse an UPDATE statement into an arena-allocated UpdateStmt.

pub fn parse_delete( input: &str, arena: &'arena Bump, ) -> Result<&'arena DeleteStmt<'arena>, ParseError>

Parse a DELETE statement into an arena-allocated DeleteStmt.

pub fn parse_replace( input: &str, arena: &'arena Bump, ) -> Result<&'arena InsertStmt<'arena>, ParseError>

Parse a REPLACE statement (alias for INSERT OR REPLACE) into an arena-allocated InsertStmt.

pub fn parse_alter_table_sql_with_interner( input: &str, arena: &'arena Bump, ) -> Result<(&'arena AlterTableStmt<'arena>, ArenaInterner<'arena>), ParseError>

Parse an ALTER TABLE statement, returning the interner for symbol resolution.

pub fn parse_delete_with_interner( input: &str, arena: &'arena Bump, ) -> Result<(&'arena DeleteStmt<'arena>, ArenaInterner<'arena>), ParseError>

Parse a DELETE statement, returning the interner for symbol resolution.

pub fn parse_update_with_interner( input: &str, arena: &'arena Bump, ) -> Result<(&'arena UpdateStmt<'arena>, ArenaInterner<'arena>), ParseError>

Parse an UPDATE statement, returning the interner for symbol resolution.

pub fn parse_insert_with_interner( input: &str, arena: &'arena Bump, ) -> Result<(&'arena InsertStmt<'arena>, ArenaInterner<'arena>), ParseError>

Parse an INSERT statement, returning the interner for symbol resolution.

pub fn parse_replace_with_interner( input: &str, arena: &'arena Bump, ) -> Result<(&'arena InsertStmt<'arena>, ArenaInterner<'arena>), ParseError>

Parse a REPLACE statement, returning the interner for symbol resolution.
