Trait conch_runtime::env::ExportedVariableEnvironment

pub trait ExportedVariableEnvironment: VariableEnvironment {
    fn exported_var(&self, name: &Self::VarName) -> Option<(&Self::Var, bool)>;
    fn set_exported_var(
        &mut self, 
        name: Self::VarName, 
        val: Self::Var, 
        exported: bool
    );
}

An interface for setting and getting shell and environment variables and controlling whether or not they can appear as environment variables to subprocesses.

Required Methods

fn exported_var(&self, name: &Self::VarName) -> Option<(&Self::Var, bool)>

Get the value of some variable and whether it is exported.

fn set_exported_var(
    &mut self,
    name: Self::VarName,
    val: Self::Var,
    exported: bool
)

Set the value of some variable, and set it's exported status as specified.
