Implementations

impl Scope

pub fn insert_var( &mut self, key: VariableKey, value: VariableValue, ) -> Option<VariableValue>

Add variable to scope

pub fn process_binding(&mut self, key: &str, value: &str) -> DevrcResult<()>

pub fn insert_env(&mut self, key: &str, value: &str) -> Option<String>

Add environment variable to scope

pub fn get_var(&self, key: &VariableKey) -> Option<&VariableValue>

pub fn get_env_var(&self, key: &str) -> Option<&String>

pub fn process_raw_vars(&mut self, variables: &RawVariables) -> DevrcResult<()>

pub fn process_raw_env_vars( &mut self, variables: &RawEnvironment<String>, ) -> DevrcResult<()>

pub fn process_rendered_env_vars( &mut self, variables: &Environment<String>, ) -> DevrcResult<()>

pub fn compute_execution_scope(&self) -> DevrcResult<Scope>

Trait Implementations

impl Clone for Scope

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Scope

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

Formats the value using the given formatter.

impl Default for Scope

fn default() -> Scope

Returns the “default value” for a type.

impl PartialEq for Scope

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

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

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

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

impl TryFrom<&Scope> for Context

type Error = DevrcError

The type returned in the event of a conversion error.

fn try_from(source: &Scope) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Scope

impl StructuralPartialEq for Scope
