Enum ThemeError 

#[non_exhaustive]
pub enum ThemeError {
    Io {
        path: String,
        source: Error,
    },
    Syntax(String),
    WrongType {
        field: String,
        expected: &'static str,
    },
    BadColor {
        field: String,
        source: ColorError,
    },
}

Why a theme could not be read.

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.

Io

The file could not be read.

Fields

path: String

What was asked for.

source: Error

Why not.

Syntax(String)

The text is not TOML.

WrongType

A field held the wrong kind of value.

Named, because a theme file is hand-written and “invalid argument” over twenty-one fields is not something a person can act on.

Fields

field: String

Which field.

expected: &'static str

What it should have been.

BadColor

A color was not readable.

Fields

field: String

Which field.

source: ColorError

Why not.

Trait Implementations

impl Debug for ThemeError

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

Formats the value using the given formatter.

impl Display for ThemeError

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

Formats the value using the given formatter.

impl Error for ThemeError

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.
