Enum UserExtensionError

pub enum UserExtensionError {
    Io {

Errors from loading config.toml’s user-extension section.

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

Filesystem read failed (other than “not found”, which is treated as “no user extensions” — see load).

Fields

path: String

The path we tried to read.

source: Error

The underlying I/O error.

Parse

TOML deserialisation failed (malformed file).

Fields

path: String

The path that failed to parse.

source: Error

The underlying TOML deserialiser error.

InvalidPatterns

One or more host patterns failed grammar validation per ADR-0028 D2-1. The vec collects every offending entry so the user sees all errors in a single pass rather than fixing them one at a time (review pass I6).

Fields

path: String

The path containing the offending entries.

issues: Vec<InvalidPatternIssue>

All rejected patterns in this file.

Trait Implementations

impl Debug for UserExtensionError

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

Formats the value using the given formatter.

impl Display for UserExtensionError

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

Formats the value using the given formatter.

impl Error for UserExtensionError

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.
