Struct EvalWorkspace 

pub struct EvalWorkspace { /* private fields */ }

Reusable workspace for expression evaluation.

Using a workspace avoids heap allocations on every evaluate() call, which is critical for performance in hot loops (generation, Newton-Raphson).

Example

use ries_rs::eval::{EvalWorkspace, evaluate_with_workspace};
use ries_rs::expr::Expression;
let mut workspace = EvalWorkspace::new();
let expressions: Vec<Expression> = vec![];
let x = 1.0_f64;
for expr in &expressions {
    let result = evaluate_with_workspace(expr, x, &mut workspace)?;
    // workspace is reused, no new allocations
}

Implementations

impl EvalWorkspace

pub fn new() -> Self

Create a new workspace with pre-allocated capacity.

Capacity of 32 handles most expressions; grows automatically if needed.

Trait Implementations

impl Default for EvalWorkspace

fn default() -> Self

Returns the “default value” for a type.
