Enum Context 

pub enum Context {
    Regular {
        positional_params: PositionalParams,
    },
    Volatile,
}

Variable context

This enum defines the type of a context. The context type affects the behavior of variable assignment. A regular context is the default context type and may have positional parameters. A volatile context is used for holding temporary variables when executing a built-in or function.

Variants

Regular

Context for normal assignments.

The base context is a regular context. Every function invocation also creates a regular context for local assignments and positional parameters.

Fields

positional_params: PositionalParams

Volatile

Context for temporary assignments.

A volatile context is used for holding temporary variables when executing a built-in or function.

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Context

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

Formats the value using the given formatter.

impl Default for Context

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Context

fn eq(&self, other: &Context) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
