Struct CompiledExpr 

Source 
pub struct CompiledExpr<K = String> { /* private fields */ }
Expand description

A compiled, executable expression that owns its variable map.

Created by Tabula::compile. Evaluation requires passing a slice of f64 values.

Implementations§

Source§

impl<K> CompiledExpr<K>

Source

pub fn vars(&self) -> &[K]

Returns a slice of variable keys in the order they must be supplied for evaluation.

Source

pub fn eval(&self, values: &[f64]) -> Result<f64, JitError>

Evaluates the compiled expression with the given values.

The values slice must provide f64 values in the exact order specified by vars().

§Errors
  • JitError::ValuesLen if values.len() is less than self.vars().len().
  • JitError::Invalidated if the expression was invalidated by Tabula::free_memory.
