Struct CgiEnvironment 

pub struct CgiEnvironment { /* private fields */ }

A map of CGI environment variables.

Implementations

impl CgiEnvironment

pub fn get(&self, key: &str) -> Option<&str>

Obtains the value of the specified environment variable.

pub fn contains_key(&self, key: &str) -> bool

Determines whether the specified environment variable exists.

pub fn iter<'a>(&'a self) -> Iter<'a, String, String>

Obtains an iterator over the environment variables.

pub fn len(&self) -> usize

Returns the total number of environment variables.

pub fn is_empty(&self) -> bool

Checks whether the environment is empty.

Trait Implementations

impl Clone for CgiEnvironment

fn clone(&self) -> CgiEnvironment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CgiEnvironment

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

Formats the value using the given formatter.

impl From<HashMap<String, String>> for CgiEnvironment

fn from(map: HashMap<String, String>) -> CgiEnvironment

Converts to this type from the input type.

impl From<LinkedHashMap<String, String>> for CgiEnvironment

fn from(map: LinkedHashMap<String, String>) -> CgiEnvironment

Converts to this type from the input type.

impl FromIterator<(String, String)> for CgiEnvironment

fn from_iter<T>(iter: T) -> CgiEnvironment

where T: IntoIterator<Item = (String, String)>,

Creates a value from an iterator.

impl Hash for CgiEnvironment

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 Index<&str> for CgiEnvironment

type Output = str

The returned type after indexing.

fn index(&self, key: &str) -> &<CgiEnvironment as Index<&str>>::Output

Performs the indexing (container[index]) operation.

impl<'a> IntoIterator for &'a CgiEnvironment

type Item = (&'a String, &'a String)

The type of the elements being iterated over.

type IntoIter = Iter<'a, String, String>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <&'a CgiEnvironment as IntoIterator>::IntoIter

Creates an iterator from a value.

impl IntoIterator for CgiEnvironment

type Item = (String, String)

The type of the elements being iterated over.

type IntoIter = IntoIter<String, String>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <CgiEnvironment as IntoIterator>::IntoIter

Creates an iterator from a value.

impl PartialEq for CgiEnvironment

fn eq(&self, other: &CgiEnvironment) -> 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.
