Enum ThemeLoadError 

#[non_exhaustive]
pub enum ThemeLoadError {
    Io(Error),
    Parse(String),
}

Available on crate feature serde only.

Error returned when loading a theme from a file or string fails.

Carries either the underlying I/O failure or a human-readable parse message. Never panics on malformed input — callers decide how to recover.

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(Error)

The theme file could not be read from disk.

Parse(String)

The document was read but is not valid TOML, or did not match the expected ThemeFile shape. The string carries the parser’s message.

Trait Implementations

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 From<Error> for ThemeLoadError

fn from(e: Error) -> Self

Converts to this type from the input type.
