Enum LockProjectionError 

#[non_exhaustive]
pub enum LockProjectionError {
    InvalidSelection,
    Parse {
        input: &'static str,
        source: Error,
    },
    MissingPackages,
    PackageSelection {
        package: String,
        matches: usize,
    },
    PreviousVersion {
        package: String,
    },
    ChangedInputs,
}

Strict version projection failed without changing either input.

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.

InvalidSelection

No changes selected, or a name/version is empty or a name repeated.

Parse

One selected input is not valid TOML.

Fields

input: &'static str

before or after input role.

source: Error

Original parser error.

MissingPackages

The saved lockfile has no package array.

PackageSelection

A name must identify exactly one unsourced package.

Fields

package: String

Requested workspace package.

matches: usize

Number of matching unsourced records.

PreviousVersion

The saved selected package does not have its expected prior version.

Fields

package: String

Requested workspace package.

ChangedInputs

The after input differs from the exact permitted projection.

Trait Implementations

impl Debug for LockProjectionError

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

Formats the value using the given formatter.

impl Display for LockProjectionError

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

Formats the value using the given formatter.

impl Error for LockProjectionError

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>)
