Enum CStandard 

pub enum CStandard {
    C89,
    C99,
    C11,
    C17,
    C23,
}

C language standards Cabin can request, oldest to newest. The Ord derive follows declaration order, which is the plain chronological chain (in particular c11 < c17). Implements the level chain Level_C of spec D2 (docs/design/standard-compatibility/spec.md): chronological enumeration order, not numeric (c89 < c11), with no equivalence special case anywhere in the chain. The c90 alias is normalized away by Self::parse and is not an element of the chain (D2 remark).

Implementations

impl CStandard

pub const ALL: [Self; 5]

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

pub fn parse(value: &str) -> Result<Self, LanguageStandardParseError>

Errors

Returns LanguageStandardParseError when value is not a recognized C standard: a dedicated variant for range-like inputs and for the interface-only none, otherwise the invalid-value error listing the accepted identifiers. c90 parses as an alias of c89, normalized immediately.

Trait Implementations

impl Clone for CStandard

fn clone(&self) -> CStandard

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CStandard

impl Debug for CStandard

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CStandard

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CStandard

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

Formats the value using the given formatter.

impl Eq for CStandard

impl FromStr for CStandard

type Err = LanguageStandardParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for CStandard

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 Ord for CStandard

fn cmp(&self, other: &CStandard) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for CStandard

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

impl PartialOrd for CStandard

fn partial_cmp(&self, other: &CStandard) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for CStandard

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
