Struct EnvItem 

pub struct EnvItem(/* private fields */);

Item in a PAM environment list.

A key-value pair representing an environment variable in a EnvList, convertible to &CStr and to a pair (key, value) of &OsStr’s.

As this struct is tightly coupled to the memory management of EnvList no constructor for custom instances is provided.

Implementations

impl EnvItem

pub fn as_cstr(&self) -> &CStr

Returns a CStr reference to the "key=value" representation.

pub fn key_value(&self) -> (&OsStr, &OsStr)

Returns a pair of references to a ("key", "value") representation.

Trait Implementations

impl AsRef<CStr> for EnvItem

fn as_ref(&self) -> &CStr

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

impl Debug for EnvItem

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

Formats the value using the given formatter.

impl Display for EnvItem

Display and string conversion of the environment variable.

Also causes .to_string() to be implemented.

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

Formats the value using the given formatter.

impl<'a> From<&'a EnvItem> for &'a CStr

fn from(item: &'a EnvItem) -> Self

Converts to this type from the input type.

impl<'a> From<&'a EnvItem> for (&'a OsStr, &'a OsStr)

fn from(item: &'a EnvItem) -> Self

Converts to this type from the input type.

impl Ord for EnvItem

fn cmp(&self, other: &Self) -> 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 EnvItem

fn eq(&self, other: &Self) -> 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 EnvItem

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