Enum SchemaLoadError 

pub enum SchemaLoadError {
    TomlParse(Error),
    Io {
        path: PathBuf,
        source: Error,
    },
    UnknownLabelRef(SmolStr),
    DuplicateLabel(SmolStr),
    DuplicateRelType(SmolStr),
    DuplicateParameter(SmolStr),
    BadType(String),
}

Errors surfaced by the TOML schema loader (spec 0002 §11).

Variants

TomlParse(Error)

The input is not well-formed TOML, or does not match the expected shape.

Io

Reading the file failed.

Fields

path: PathBuf

Path we tried to read.

source: Error

Underlying I/O error.

UnknownLabelRef(SmolStr)

A relationship type references an undeclared label.

DuplicateLabel(SmolStr)

A label name is declared twice.

DuplicateRelType(SmolStr)

A rel type name is declared twice.

DuplicateParameter(SmolStr)

A parameter name is declared twice.

BadType(String)

A type string lies outside the grammar in spec 0002 §4, or [meta].cyrs_schema_version does not match the supported version.

Trait Implementations

impl Debug for SchemaLoadError

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

Formats the value using the given formatter.

impl Display for SchemaLoadError

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

Formats the value using the given formatter.

impl Error for SchemaLoadError

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<BuilderError> for SchemaLoadError

fn from(err: BuilderError) -> Self

Converts to this type from the input type.

impl From<Error> for SchemaLoadError

fn from(source: Error) -> Self

Converts to this type from the input type.
