Implementations

impl TaskEnv

pub fn new() -> Self

Create an empty environment.

pub fn len(&self) -> usize

Returns the number of key–value pairs.

pub fn is_empty(&self) -> bool

Returns true if the environment has no entries.

pub fn iter(&self) -> impl Iterator<Item = &KeyValue>

Iterate over all key–value pairs in insertion order.

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

Get the value for a key, returning the last matching entry (last-wins override semantics).

pub fn push<K, V>(&mut self, key: K, value: V)

where K: Into<String>, V: Into<String>,

Append a key–value pair.

impl TaskEnv

pub fn single<K, V>(key: K, value: V) -> Self

where K: Into<String>, V: Into<String>,

Create an environment containing a single key–value pair.

Trait Implementations

impl Clone for TaskEnv

fn clone(&self) -> TaskEnv

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TaskEnv

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

Formats the value using the given formatter.

impl Default for TaskEnv

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TaskEnv

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> IntoIterator for &'a TaskEnv

type Item = &'a KeyValue

The type of the elements being iterated over.

type IntoIter = Iter<'a, KeyValue>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for TaskEnv

fn eq(&self, other: &TaskEnv) -> 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 Serialize for TaskEnv

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for TaskEnv
