Implementations

impl Args

pub fn new() -> Self

Create new, empty Args.

pub fn get<V: FromStr<Err = impl Error>>(
    &self,
    key: impl AsRef<str>
) -> Result<V, Error>

Try to get a value of type V that is tried to be parsed from the string mapped by the key.

pub fn set<K: Into<String>, V: Into<String>>(
    &mut self,
    key: K,
    value: V
) -> Option<String>

Map the key the stringified value.

pub fn remove<K: AsRef<str>>(&mut self, key: K) -> Option<String>

Remove the key together with its associated value.

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

Iterate over key-value pairs of the Args.

pub fn iter_mut(&mut self) -> IterMut<'_, String, String>

Iterate mutably over key-value pairs of the Args.

pub fn map(&self) -> &HashMap<String, String>

Get a reference to the underlying HashMap.

pub fn deserialize<D: for<'a> Deserialize<'a>>(&self) -> Option<D>

Try to Deserialize a value of type D from the JSON-serialized Args.
