Struct cfg_expr::targets::Env

pub struct Env(pub Cow<'static, str>);

The “environment” field, which specifies an ABI environment on top of the operating system. In many configurations, this field is omitted, and the environment is implied by the operating system.

pub fn as_str(&self) -> &str

Returns the string for the field.

Trait Implementations

impl AsRef<str> for Env

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Env

fn clone(&self) -> Env

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Env

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

impl Display for Env

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

Formats the value using the given formatter.

impl Hash for Env

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, 

Feeds a slice of this type into the given Hasher.

impl Ord for Env

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<Env> for Env

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

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

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

This method tests for !=.

impl PartialOrd<Env> for Env

fn partial_cmp(&self, other: &Env) -> 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
