Enum ConfigValueType 

pub enum ConfigValueType {
    String,
    Bool,
    Integer,
    StringList,
}

The value type of a configurable setting. Drives CLI parsing, validation, and display.

Variants

String

A single string.

Bool

A boolean (true/false).

Integer

A signed integer.

StringList

A list of strings (CLI input accepts a JSON array or a comma-separated list).

Implementations

impl ConfigValueType

pub fn label(self) -> &'static str

Short human label for help/listing output.

pub fn from_label(label: &str) -> Option<ConfigValueType>

Inverse of label: recover a type from its short label.

pub fn parse(self, raw: &str) -> Result<Value, String>

Parse a raw CLI string into a JSON value of this type. Returns a human-readable error string on mismatch so meta config set can reject bad input before writing.

pub fn matches(self, value: &Value) -> bool

True if an existing JSON value already matches this type.

Trait Implementations

impl Clone for ConfigValueType

fn clone(&self) -> ConfigValueType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ConfigValueType

impl Debug for ConfigValueType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ConfigValueType

fn deserialize<__D>( __deserializer: __D, ) -> Result<ConfigValueType, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ConfigValueType

impl PartialEq for ConfigValueType

fn eq(&self, other: &ConfigValueType) -> 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 ConfigValueType

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
