Enum ConversionErrorKind

Source

#[non_exhaustive]pub enum ConversionErrorKind {
    FailedToUnescape(EscapeError),
    InvalidLiteralKind,
}

🔬This is a nightly-only experimental API. (proc_macro_value #136652)

Expand description

Errors returned when trying to retrieve a literal unescaped value.

Variants (Non-exhaustive)§

This enum is marked as 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.

§

FailedToUnescape(EscapeError)

🔬This is a nightly-only experimental API. (proc_macro_value #136652)

The literal failed to be escaped, take a look at EscapeError for more information.

§

InvalidLiteralKind

🔬This is a nightly-only experimental API. (proc_macro_value #136652)

Trying to convert a literal with the wrong type.
