Enum ProjectError 

pub enum ProjectError {
    UnknownProject {
        reference: String,
    },
    UnknownIssue {
        selector: u32,
    },
    InvalidDates {
        detail: String,
    },
    DuplicateName {
        name: String,
    },
}

Why a project operation was refused.

The variants map one-to-one onto ProjectDiagnosticKind, so a surface can print the named kind without a second classification step.

Variants

UnknownProject

A project reference did not resolve.

Fields

reference: String

The reference exactly as the caller wrote it.

UnknownIssue

An issue selector named no issue in the snapshot.

Fields

selector: u32

The selector exactly as the caller wrote it.

InvalidDates

The start/due dates are malformed or inverted.

Fields

detail: String

The shared date rule’s message.

DuplicateName

The name is blank, padded, or already in use.

Fields

name: String

The name as supplied.

Implementations

impl ProjectError

pub fn kind(&self) -> ProjectDiagnosticKind

The named diagnostic kind this refusal reports.

pub fn message(&self) -> String

The single wording for this refusal, via the kind’s helper.

Trait Implementations

impl Clone for ProjectError

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 ProjectError

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

Formats the value using the given formatter.

impl Display for ProjectError

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

Formats the value using the given formatter.

impl Eq for ProjectError

impl Error for ProjectError

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<ProjectError> for TixError

A project refusal becomes user input error, so ? works at the call site.

The payload is a single-line diagnostic (<kind>: <message>), so it takes the crate’s existing invalid input: prefix without doubling it — the same boundary every other selector/validation refusal crosses (cli-surface §6).

fn from(err: ProjectError) -> TixError

Converts to this type from the input type.

impl PartialEq for ProjectError

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

Equality operator ==.

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

Inequality operator !=.
