Expand description

Trait that parsers must implement to use logical expression parsing

Required Methods§

Source

fn current_token(&self) -> &Token

Source

fn advance(&mut self)

Source

fn consume(&mut self, expected: Token) -> Result<(), String>

Source

fn parse_logical_and(&mut self) -> Result<SqlExpression, String>

Source

fn parse_base_logical_expression(&mut self) -> Result<SqlExpression, String>

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
