Enum Features 

pub enum Features {
    CompilerBuiltinsMem,
    CompilerBuiltinsC,
    CompilerBuiltinsNoAsm,
}

Features to enable when building the sysroot crates

See SysrootBuilder::features for usage.

Variants

CompilerBuiltinsMem

This enables the mem feature of compiler_builtins, which will provide memory related intrinsics such as memcpy.

CompilerBuiltinsC

This enables the c feature of compiler_builtins, which enables compilation of C code and may result in more optimized implementations, and fills in the rare unimplemented intrinsics.

CompilerBuiltinsNoAsm

This enables the no-asm feature of compiler_builtins, which disables any implementations which use inline assembly and fall back to pure Rust versions (if available).

Trait Implementations

impl Clone for Features

fn clone(&self) -> Features

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Features

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

Formats the value using the given formatter.

impl Ord for Features

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

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

fn partial_cmp(&self, other: &Features) -> 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.
