Why a target cannot be found, read or written.

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.

NotFound

No directory from here up holds .devset/config.toml.

Fields

dir: Utf8PathBuf

Where the search began.

Nested

A new target would lie inside another.

Fields

dir: Utf8PathBuf

The directory asked for.

root: Utf8PathBuf

The enclosing target’s root.

OldConfig

config.toml is devset 0.1’s: its layers name locations, not profiles.

NoSuchSource

A layer, or a command, names a source [sources] does not.

Fields

name: SourceName

The name asked for.

sources: Vec<SourceName>

Every source’s name.

layers: Vec<ProfileRef>

The layers config.toml names it for.

SourceExists

[sources] already names another source so.

Fields

name: SourceName

The name.

location: String

The source it names, as configured.

WhichSource

A profile is named without its source, and the target names several, or none.

Fields

profile: ProfileName

The profile.

sources: Vec<SourceName>

Every source the target names.

Ambiguous

A source holds several profiles, and none was named.

Fields

location: String

The source, as configured.

profiles: Vec<ProfileName>

Every profile it holds.

DuplicateLayer

config.toml already lists the layer.

Fields

layer: ProfileName

The layer’s profile.

LayerTwice

config.toml lists one layer twice, which a layer’s name must tell apart.

Fields

layer: ProfileName

The layer’s profile.

NotListed

A feature to turn off that the layer does not list.

Fields

layer: ProfileName

The layer’s profile.

feature: FeatureName

The feature.

listed: Vec<FeatureName>

The features the layer lists.

NoSuchLayer

No layer, and no source, has the name asked for.

Fields

name: String

The name asked for.

names: Vec<String>

Every layer’s name, and every source’s.

NoSuchScaffold

A scaffold named on the command line is no active profile’s.

Fields

name: String

The name asked for, profile/group.

scaffolds: Vec<String>

Every active profile’s scaffolds.

NotManaged

A path named on the command line is not a file devset manages.

Fields

path: String

The path, as given.

managed: Vec<RelPath>

Every managed path.

Required

A layer named where only a configured one will do is one another profile requires.

Fields

name: ProfileName

The layer asked for.

by: ProfileName

The profile that requires it.

StaleOverride

config.toml overrides a path no layer provides.

Fields

path: RelPath

The overridden path.

provided: Vec<RelPath>

Every path the layers provide.

NotAFile

A managed path on disk is a symlink, a directory or a special file.

Fields

path: RelPath

The managed path.

kind: &'static str

What is there instead: a symlink, a directory or a special file.

Busy

Another devset holds the target’s lock.

Concurrent

state.toml changed while this devset ran.

Trait Implementations

impl Clone for TargetError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TargetError

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

Formats the value using the given formatter.

impl Display for TargetError

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

Formats the value using the given formatter.

impl Eq for TargetError

impl Error for TargetError

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<TargetError> for Error

fn from(source: TargetError) -> Self

Converts to this type from the input type.

impl PartialEq for TargetError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
