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.

LimitExceeded

An input exceeds the caller’s per-document byte allowance.

Fields

input: &'static str

original or candidate input role.

limit: usize

Caller-selected byte allowance.

Utf8

An input is not UTF-8.

Fields

input: &'static str

Input role.

source: Utf8Error

Original decoding failure.

Parse

An input is not valid TOML.

Fields

input: &'static str

Input role.

source: Error

Original parser failure.

MissingPackages

An input has no package array.

Fields

input: &'static str

Input role.

InvalidPackage

A package record or external identity field is malformed.

Fields

input: &'static str

Input role.

index: usize

Zero-based package-array position.

reason: &'static str

Failed structural or field requirement.

DuplicateSelection

An external name/version/source identity appears more than once.

Fields

input: &'static str

Input role.

package: String

Package name.

version: String

Package version.

SelectionChanged

A candidate identity or checksum does not match the original.

Fields

package: String

Candidate package name.

version: String

Candidate package version.

Trait Implementations

impl Debug for ExternalLockError

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

Formats the value using the given formatter.

impl Display for ExternalLockError

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

Formats the value using the given formatter.

impl Error for ExternalLockError

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.
