Implementations

impl ExperimentalFeatures

pub fn new( manifest: &HashMap<String, bool>, cli_experimental: &[Feature], cli_no_experimental: &[Feature], ) -> Result<ExperimentalFeatures, Error>

Experimental features will be applied in the following order: 1 - manifest (no specific order) 2 - cli_no_experimental 3 - cli_experimental 4 - FORC_NO_EXPERIMENTAL (env var) 5 - FORC_EXPERIMENTAL (env var)

impl ExperimentalFeatures

pub fn set_enabled_by_name( &mut self, feature: &str, enabled: bool, ) -> Result<(), Error>

pub fn set_enabled(&mut self, feature: Feature, enabled: bool)

pub fn is_enabled_for_cfg(&self, cfg: &str) -> Result<bool, Error>

Used for testing if a #[cfg(...)] feature is enabled. Already prepends “experimental_” to the feature name.

pub fn with_new_encoding(self, enabled: bool) -> Self

pub fn with_references(self, enabled: bool) -> Self

pub fn with_error_type(self, enabled: bool) -> Self

pub fn with_const_generics(self, enabled: bool) -> Self

impl ExperimentalFeatures

pub fn parse_from_package_manifest( &mut self, experimental: &HashMap<String, bool>, ) -> Result<(), Error>

pub fn parse_from_environment_variables(&mut self) -> Result<(), Error>

Enable and disable features using comma separated feature names from environment variables “FORC_EXPERIMENTAL” and “FORC_NO_EXPERIMENTAL”.

pub fn parse_comma_separated_list( &mut self, features: impl AsRef<str>, enabled: bool, ) -> Result<(), Error>

Trait Implementations

impl Clone for ExperimentalFeatures

fn clone(&self) -> ExperimentalFeatures

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExperimentalFeatures

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

Formats the value using the given formatter.

impl Default for ExperimentalFeatures

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for ExperimentalFeatures

fn eq(&self, other: &ExperimentalFeatures) -> 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.
