RustCold

For things unlikely to be called, where reducing register pressure in extern "Rust" callers is worth paying extra cost in the callee. Stronger than just #[cold] because fn pointers might be incompatible.

Implementations

impl Abi

pub fn supports_varargs(self) -> bool

impl Abi

pub const FALLBACK: Abi = _

Default ABI chosen for extern fn declarations without an explicit ABI.

pub fn index(self) -> usize

pub fn data(self) -> &'static AbiData

pub fn name(self) -> &'static str

Trait Implementations

impl Clone for Abi

fn clone(&self) -> Abi

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Abi

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

Formats the value using the given formatter.

impl<__D: Decoder> Decodable<__D> for Abi

fn decode(__decoder: &mut __D) -> Self

impl Display for Abi

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

Formats the value using the given formatter.

impl<__E: Encoder> Encodable<__E> for Abi

fn encode(&self, __encoder: &mut __E)

impl Hash for Abi

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<__CTX> HashStable<__CTX> for Abiwhere __CTX: HashStableContext,

fn hash_stable(&self, __hcx: &mut __CTX, __hasher: &mut StableHasher)

impl Ord for Abi

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Abi> for Abi

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<Abi> for Abi

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Copy for Abi

impl Eq for Abi

impl StructuralEq for Abi

impl StructuralPartialEq for Abi

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.
