Enum ArgumentValue

pub enum ArgumentValue<'a> {
    String(&'a str),
    Integer(i32),
    Boolean(bool),
    Null,
}

A type for possible values an argument key could have.

Those consuming values should attempt to be flexible when accepting values. For instance a truthy key should accept 1, true, and Null (as it indicates that they key is present at all) as meaning “true”.

Variants

String(&'a str)

A string argument value.

Integer(i32)

An integer argument value.

Boolean(bool)

A boolean argument value.

Null

No value explicitly passed for this argument. It notes that the key was included in the mapping.

Trait Implementations

impl<'a> Clone for ArgumentValue<'a>

fn clone(&self) -> ArgumentValue<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for ArgumentValue<'a>

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

Formats the value using the given formatter.

impl<'a> From<&'a str> for ArgumentValue<'a>

fn from(value: &'a str) -> Self

Converts to this type from the input type.

impl From<()> for ArgumentValue<'_>

fn from(_: ()) -> Self

Converts to this type from the input type.

impl<'a> From<Option<&'a str>> for ArgumentValue<'a>

fn from(value: Option<&'a str>) -> Self

Converts to this type from the input type.

impl From<bool> for ArgumentValue<'_>

fn from(value: bool) -> Self

Converts to this type from the input type.

impl From<i32> for ArgumentValue<'_>

fn from(value: i32) -> Self

Converts to this type from the input type.

impl<'a> PartialEq for ArgumentValue<'a>

fn eq(&self, other: &ArgumentValue<'a>) -> 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.
