Enum GffDocumentError 

pub enum GffDocumentError {
    Syntax(GffPathParseError),
    Path(GffPathError),
    WrongType {
        at: String,
        wanted: &'static str,
    },
}

A path that does not parse, or does not name one field of this tree.

Variants

Syntax(GffPathParseError)

The path text is not an address.

Path(GffPathError)

The address does not resolve, or the tree will not take the edit.

WrongType

The field is there and holds something the caller cannot read it as.

Separate from the address not resolving, because those want different answers: a missing field is often ordinary and a field of the wrong width is a file that is not what it claimed to be.

Fields

at: String

The address that resolved.

wanted: &'static str

The type the caller asked for.

Trait Implementations

impl Clone for GffDocumentError

fn clone(&self) -> GffDocumentError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GffDocumentError

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

Formats the value using the given formatter.

impl Display for GffDocumentError

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

Formats the value using the given formatter.

impl Error for GffDocumentError

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<GffPathError> for GffDocumentError

fn from(source: GffPathError) -> Self

Converts to this type from the input type.

impl From<GffPathParseError> for GffDocumentError

fn from(source: GffPathParseError) -> Self

Converts to this type from the input type.

impl PartialEq for GffDocumentError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
