Enum ConfigValueError 

#[non_exhaustive]
pub enum ConfigValueError {
    InvalidBool {
        value: String,
    },
    EmptyInteger,
    InvalidInteger {
        value: String,
    },
    IntegerOverflow {
        value: String,
    },
    InvalidColor {
        value: String,
    },
}

Why a raw config value could not be read as a boolean, integer or color.

Returned by crate::config::parse_bool, crate::config::parse_i64 and crate::config::parse_color, which see only the value. Readers that also know the key (crate::config::ConfigSet::get_bool, crate::config::ConfigSet::get_i64) wrap it in ConfigError::InvalidValue.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidBool

Not one of the boolean words (true/yes/on, false/no/off) or an integer.

Fields

value: String

Raw config value that could not be parsed.

EmptyInteger

An integer was required but the value is empty or only whitespace.

InvalidInteger

Not a decimal integer with an optional k/m/g suffix.

Fields

value: String

Raw config value (trimmed) that could not be parsed.

IntegerOverflow

The integer does not fit in an i64 once its k/m/g suffix is applied.

Fields

value: String

Raw config value (trimmed) that overflowed.

InvalidColor

Not a color specification (color names, numbers or #rrggbb, plus attributes).

Fields

value: String

Raw config value (trimmed) that could not be parsed.

Implementations

impl ConfigValueError

pub fn for_key(self, key: impl Into<String>) -> ConfigError

Attach the config key whose value was rejected.

Parameters

• key: the config key as the caller spelled it (for example core.bare).

Returns

ConfigError::InvalidValue carrying key and this error as its source.

Trait Implementations

impl Clone for ConfigValueError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConfigValueError

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

Formats the value using the given formatter.

impl Display for ConfigValueError

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

Formats the value using the given formatter.

impl Eq for ConfigValueError

impl Error for ConfigValueError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for ConfigValueError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
