Variants

Io

An I/O error with additional context about the operation.

IoPath

An I/O error with path context.

Fields

message: String

A human-readable description of the failed I/O operation.

path: PathBuf

The file or directory path involved in the I/O operation.

error: Error

The underlying I/O error.

Utf8

A UTF-8 decoding error.

Fields

message: String

A human-readable description of the UTF-8 decoding failure.

error: FromUtf8Error

The underlying UTF-8 error.

Server(String)

Trait Implementations

impl Debug for EuvError

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

Formats the value using the given formatter.

impl Display for EuvError

Implements Display for EuvError to provide human-readable error messages.

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

Formats the error message based on the variant.

Arguments

• &mut std::fmt::Formatter - The formatter.

Returns

• std::fmt::Result - The result of the formatting operation.

impl Error for EuvError

Implements Error for EuvError so it integrates with the Rust error ecosystem.

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

Returns

• Option<&(dyn std::error::Error + 'static)> - The underlying error source.

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 EuvError

Implements From<notify::Error> for EuvError to enable ? operator conversion.

fn from(error: Error) -> Self

Converts a notify::Error into EuvError::Watch.

Arguments

• notify::Error - The file watcher error to convert.

Returns

• EuvError - The converted Watch variant.
