Struct EvalContext 

pub struct EvalContext<'a> {
    pub trig_argument_scale: f64,
    pub user_constants: &'a [UserConstant],
    pub user_functions: &'a [UserFunction],
}

Explicit evaluation context for a single run.

This keeps trig scaling and user-defined symbols inside the function signature instead of relying on process-global evaluator state.

Fields

trig_argument_scale: f64

Argument scale for sinpi/cospi/tanpi.

user_constants: &'a [UserConstant]

User-defined constants available during evaluation.

user_functions: &'a [UserFunction]

User-defined functions available during evaluation.

Implementations

impl EvalContext<'static>

pub fn new() -> Self

Create a default context with built-in trig semantics and no user symbols.

impl<'a> EvalContext<'a>

pub fn from_slices( user_constants: &'a [UserConstant], user_functions: &'a [UserFunction], ) -> Self

Create a context from user-defined constants and functions.

pub fn with_trig_argument_scale(self, scale: f64) -> Self

Override the trig argument scale for this evaluation context.

Trait Implementations

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for EvalContext<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for EvalContext<'static>

fn default() -> Self

Returns the “default value” for a type.
