A tracker that combines both token and recursion tracking.

Required Associated Types

type Error

The error type returned when either limit is exceeded.

Required Methods

fn increase_token(&mut self)

Increases the token count.

fn increase_recursion(&mut self)

Increases the recursion depth.

fn decrease_recursion(&mut self)

Decreases the recursion depth.

fn check(&self) -> Result<(), Self::Error>

Checks if any of the limits have been exceeded.

Provided Methods

fn increase_token_and_decrease_recursion(&mut self)

Increase the token count and decrease recursion depth.

fn increase_token_and_decrease_recursion_and_check( &mut self, ) -> Result<(), Self::Error>

Increases the token count and decreases recursion depth and checks limits.

fn increase_token_and_check(&mut self) -> Result<(), Self::Error>

Increases the token count and checks limits.

fn increase_both(&mut self)

Increases the token count and recursion depth, then checks limits.

fn increase_both_and_check(&mut self) -> Result<(), Self::Error>

Increase the token count, decrease recursion depth, then checks limits.
