Enum CfgAbi 

pub enum CfgAbi {
    Abi64,
    AbiV2,
    AbiV2Hf,
    Eabi,
    EabiHf,
    ElfV1,
    ElfV2,
    Fortanix,
    Ilp32,
    Ilp32e,
    Llvm,
    MacAbi,
    Sim,
    SoftFloat,
    Spe,
    Uwp,
    VecDefault,
    VecExtAbi,
    X32,
    Unspecified,
    Other(Cow<'static, str>),
}

An enum representing possible values for cfg(target_abi). This field is not forwarded to LLVM so it does not by itself affect codegen. See the cfg_abi field of TargetOptions for more details.

The vast majority of the time, the compiler deals with a fixed set of values, so it is convenient for them to be represented in an enum. However, it is possible to have arbitrary values in a target JSON file (which can be parsed when --target is specified). This might occur, for example, for an out-of-tree codegen backend that supports a value (e.g. architecture or OS) that rustc currently doesn’t know about. This variant exists as an escape hatch for such cases.

Implementations

impl CfgAbi

pub fn desc(&self) -> &str

impl CfgAbi

pub fn desc_symbol(&self) -> Symbol

Trait Implementations

impl Clone for CfgAbi

fn clone(&self) -> CfgAbi

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CfgAbi

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CfgAbi

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CfgAbi

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

Formats the value using the given formatter.

impl FromStr for CfgAbi

type Err = Infallible

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 CfgAbi

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 JsonSchema for CfgAbi

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn json_schema(_: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

impl Ord for CfgAbi

fn cmp(&self, other: &CfgAbi) -> 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 CfgAbi

fn eq(&self, other: &CfgAbi) -> 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 CfgAbi

fn partial_cmp(&self, other: &CfgAbi) -> 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 ToJson for CfgAbi

fn to_json(&self) -> Json

impl Eq for CfgAbi

impl StructuralPartialEq for CfgAbi

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
