Enum PrompterError 

pub enum PrompterError {
    Io {
        path: PathBuf,
        source: Error,
    },
    Write(Error),
    HomeNotSet,
    WorkingDir(Error),
    NoParentDir(PathBuf),
    InvalidToml(Error),
    ConfigField(String),
    DuplicateProfile(String),
    ImportCycle(PathBuf),
    Resolve(ResolveError),
    Validation(String),
    Json(Error),
    ArgParse(String),
}

All errors that can occur during prompter configuration loading, profile resolution, rendering, and scaffolding.

Each variant names a distinct failure mode a caller might branch on. Variants that carry a bare String do so only for human-facing context (a library/serializer message, a clap usage string) that callers merely display rather than match on.

Variants

Io

An I/O operation failed, annotated with the path it concerned.

Fields

path: PathBuf

The filesystem path the failing operation targeted.

source: Error

The underlying I/O error.

Write(Error)

A write to an output sink failed.

HomeNotSet

The home directory could not be located ($HOME unset).

WorkingDir(Error)

The current working directory could not be resolved.

NoParentDir(PathBuf)

A config file path lacked a parent directory.

InvalidToml(Error)

The TOML in a config file was syntactically invalid.

ConfigField(String)

A reserved top-level config field had the wrong type or shape.

DuplicateProfile(String)

A profile name was defined more than once across the merged bundle.

ImportCycle(PathBuf)

An import chain referred back to a config file already being loaded.

Resolve(ResolveError)

A profile dependency could not be resolved.

Validation(String)

Validation found one or more problems; the message aggregates them.

Json(Error)

A value could not be serialized to JSON.

ArgParse(String)

Command-line arguments could not be parsed; the payload is clap’s formatted usage/error text, shown to the user verbatim.

Trait Implementations

impl Debug for PrompterError

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

Formats the value using the given formatter.

impl Display for PrompterError

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

Formats the value using the given formatter.

impl Error for PrompterError

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.
