Struct cfg_expr::targets::Env

pub struct Env<'a>(pub &'a 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.

Trait Implementations

impl<'a> Clone for Env<'a>

fn clone(&self) -> Env<'a>

Returns a copy of the value.

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

impl<'a> Debug for Env<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for Env<'a>

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<'a> Ord for Env<'a>

fn cmp(&self, other: &Env<'a>) -> 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<'a> PartialEq<Env<'a>> for Env<'a>

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

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

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

This method tests for !=.

impl<'a> PartialOrd<Env<'a>> for Env<'a>

fn partial_cmp(&self, other: &Env<'a>) -> 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.
