Struct EnvVars 

pub struct EnvVars<'a>(/* private fields */);

A restricted view of Environment that exposes only variable operations.

Passed to CommandHandlerWithEnv closures so that handlers can read and write REXX variables without access to ADDRESS routing, PROCEDURE scoping, or other evaluator-internal state.

Implementations

impl<'a> EnvVars<'a>

pub fn get(&self, name: &str) -> RexxValue

Get a simple variable’s value.

pub fn set(&mut self, name: &str, value: RexxValue)

Set a simple variable.

pub fn get_compound(&self, stem: &str, resolved_tail: &str) -> RexxValue

Get a compound variable: stem.tail.

pub fn set_compound( &mut self, stem: &str, resolved_tail: &str, value: RexxValue, )

Set a compound variable.

pub fn set_stem_default(&mut self, stem: &str, value: RexxValue)

Set the default value for a stem (e.g., stem. = 0).

pub fn drop(&mut self, name: &str)

Drop (unset) a variable.

pub fn is_set(&self, name: &str) -> bool
