Struct ExprVM 

pub struct ExprVM { /* private fields */ }

Implementations

impl ExprVM

pub fn new() -> Self

Create a new VM with default stack capacity Uses inline storage for up to 16 stack values and 8 args (no heap allocation)

pub fn with_capacity(capacity: usize) -> Self

Create a VM with specific stack capacity If capacity > 16, will spill to heap when needed

pub fn execute( &mut self, program: &Program, ctx: &ExecuteContext<'_>, ) -> Result<Value>

Execute a program and return the result

pub fn execute_cow<'a>( &mut self, program: &'a Program, ctx: &'a ExecuteContext<'a>, ) -> Result<Value>

Execute a program using borrowed values where possible (Cow-based stack)

This version avoids cloning values from the row when possible. Values are only cloned when they need to be modified or passed to functions.

pub fn execute_bool( &mut self, program: &Program, ctx: &ExecuteContext<'_>, ) -> Result<bool>

Execute and return boolean result (for WHERE clauses)

This method is optimized for common filter patterns, avoiding the full VM loop overhead for simple comparisons.

pub fn execute_bool_checked( &mut self, program: &Program, ctx: &ExecuteContext<'_>, ) -> Result<bool>

Like execute_bool but returns errors instead of swallowing them.

Used by RowFilter::matches_checked to propagate VM errors (e.g. invalid REGEXP patterns) through the query result iterator.

Trait Implementations

impl Default for ExprVM

fn default() -> Self

Returns the “default value” for a type.
