Enum ProcessError 

#[non_exhaustive]
pub enum ProcessError {
    DirectoryCreation {
        dir_type: String,
        path: String,
        source: Error,
    },
    MissingArgument(String),
    CompilationError(String),
    IoError(Error),
    FrontmatterError(String),
}

Represents errors that may occur during argument processing.

Marked #[non_exhaustive] so new error cases can be added in minor versions. Consumers should always include a wildcard arm.

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.

DirectoryCreation

Occurs when a directory cannot be created.

Fields

• dir_type: The type of directory (e.g., “content”, “output”).
• path: The file path where the directory creation failed.

Fields

dir_type: String

Type of the directory, such as “content” or “output”.

path: String

Path where the directory creation failed.

source: Error

The underlying IO error that occurred.

MissingArgument(String)

Triggered when a required command-line argument is missing.

Fields

• The name of the missing argument.

CompilationError(String)

Represents a failure during the compilation process.

Fields

• Compilation error message.

IoError(Error)

Wraps underlying I/O errors.

FrontmatterError(String)

Represents a failure during the frontmatter processing.

Trait Implementations

impl Debug for ProcessError

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

Formats the value using the given formatter.

impl Display for ProcessError

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

Formats the value using the given formatter.

impl Error for ProcessError

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 From<Error> for ProcessError

fn from(e: Error) -> Self

Converts to this type from the input type.
