Enum CjseqError 

pub enum CjseqError {
    Json(Error),
    GeometryDepth {
        geometry_type: GeometryType,
        expected: usize,
        found: usize,
    },
    Io(Error),
    Validation(String),
}

The crate’s error type.

Implemented by hand: this crate does not hand-write serde impls, and it does not take a derive dependency for its error type either.

Variants

Json(Error)

A value was not the JSON the type expected, and nothing more specific could be said about why.

GeometryDepth

A geometry’s boundaries were nested to a depth its type does not allow. serde reports this as “invalid type: integer, expected a sequence”, which names neither the geometry nor the depth it wanted; this variant names both.

Fields

geometry_type: GeometryType

expected: usize

The nesting depth the geometry type requires.

found: usize

The nesting depth the boundaries actually had.

Io(Error)

An I/O operation failed, eg opening or reading a CityJSON(Seq) file.

Validation(String)

A document parsed as valid JSON, and every typed field on it parsed fine, but it still fails a structural rule this crate enforces beyond what serde alone can express – eg its type is not "CityJSON", or its version is not one this crate supports.

Trait Implementations

impl Debug for CjseqError

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

Formats the value using the given formatter.

impl Display for CjseqError

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

Formats the value using the given formatter.

impl Error for CjseqError

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 CjseqError

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<Error> for CjseqError

fn from(e: Error) -> Self
