Trait Implementations

impl Clone for Parameters

fn clone(&self) -> Parameters

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Parameters

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

Formats the value using the given formatter.

impl Default for Parameters

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Parameters

where Parameters: Default,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromArgValue for Parameters

fn from_arg_value(value: &str) -> Result<Self, String>

Construct the type from a commandline value, returning an error string on failure.

impl Serialize for Parameters

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
