Enum Error 

pub enum Error {
    Validation(Vec<FieldError>),
    ProjectNotFound(String),
    NamedNotFound(String),
    NotFound,
    WriterGone,
    SchemaUnknown {
        found: Vec<i64>,
        expected: i64,
    },
    Sqlite(Error),
    Json(Error),
}

Variants

Validation(Vec<FieldError>)

One or more changeset-style validation failures. The Elixir side returns {:error, %Ecto.Changeset{errors: [...]}}; we carry the equivalent (field, message) pairs so callers (and tests) can assert on the same field/message contract.

ProjectNotFound(String)

{:error, :project_not_found} / Repo.rollback(:project_not_found).

NamedNotFound(String)

A lookup that can name the missing identity.

NotFound

{:error, :not_found}.

WriterGone

The writer task is gone (channel closed). Should not happen in normal operation; surfaced so callers can fail loudly rather than hang.

SchemaUnknown

The schema_migrations ledger holds a version this build has never heard of and that is older than its own — the database was not written by any cliban we recognize. (A newer version is fine; see crate::migrations::run.)

Fields

found: Vec<i64>

expected: i64

Sqlite(Error)

Json(Error)

Implementations

impl Error

pub fn validation(field: &str, message: &str) -> Self

Construct a single-field validation error, mirroring Ecto.Changeset.add_error(cs, field, msg).

pub fn has_validation(&self, field: &str, needle: &str) -> bool

True if this is a validation error mentioning field with a message that contains needle. Test convenience that mirrors the Elixir tests’ cs.errors[:field] =~ needle assertions.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
