Enum LanguageStandard 

pub enum LanguageStandard {
    C(CStandard),
    Cxx(CxxStandard),
}

One per-compile standard value, carried by the build IR. Encodes the source language, so the dialect lowering derives both the rule kind and the standard flag from this single field.

Variants

C(CStandard)

Cxx(CxxStandard)

Implementations

impl LanguageStandard

pub const fn language(self) -> SourceLanguage

pub const fn as_str(self) -> &'static str

pub const fn msvc_spelling(self) -> Option<&'static str>

The /std: value cl.exe accepts for this standard, when a stable one exists. None marks the MSVC-dialect gaps (C89/C99/C23, C++98/11/23/26); the planner rejects those before lowering on the MSVC dialect.

Trait Implementations

impl Clone for LanguageStandard

fn clone(&self) -> LanguageStandard

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LanguageStandard

impl Debug for LanguageStandard

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

Formats the value using the given formatter.

impl Display for LanguageStandard

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

Formats the value using the given formatter.

impl Eq for LanguageStandard

impl Hash for LanguageStandard

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for LanguageStandard

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