Enum CoreError 

pub enum CoreError {
    Config(String),
    PathResolution(String),
    Io(Error),
}

Re-export of CoreError — the unified error type for dscode-core.

All fallible operations in this crate return Result<T, CoreError>. The unified error type for all fallible operations in dscode-core.

Every public function in this crate that can fail returns a Result<T, CoreError>. The variants cover configuration errors, path resolution failures, and I/O errors from the underlying filesystem.

Display

Each variant implements std::fmt::Display via thiserror, so calling .to_string() on a CoreError produces a human-readable message suitable for logging or displaying to the user.

Conversion

CoreError implements From<std::io::Error> so I/O errors can be propagated with the ? operator. It also implements Into<String> for ergonomic string conversion.

Variants

Config(String)

A configuration error, such as an invalid setting value or a missing required field in a configuration file.

The contained String describes the specific configuration problem.

PathResolution(String)

A platform-specific directory path could not be resolved.

This typically occurs when the home directory is unavailable or a user-configured path (e.g. ~ expansion) cannot be expanded.

The contained String describes which path failed and why.

Io(Error)

An I/O error occurred during a file or directory operation.

This variant wraps std::io::Error and is automatically created via the ? operator on any I/O call that fails (e.g. creating directories, reading configuration files).

Trait Implementations

impl Debug for CoreError

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

Formats the value using the given formatter.

impl Display for CoreError

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

Formats the value using the given formatter.

impl Error for CoreError

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<CoreError> for String

Allows converting a CoreError into a String for ergonomic error reporting.

This is useful when a string representation of the error is needed without preserving the typed error value.

fn from(err: CoreError) -> Self

Converts to this type from the input type.

impl From<Error> for CoreError

fn from(source: Error) -> Self

Converts to this type from the input type.
