Enum LeafError 

pub enum LeafError {
    UnknownFormat {
        name: String,
    },
    Parse {
        message: String,
    },
}

A parse failure constructing a document — the only fallible entry point. Every other method is infallible (it operates on an already-parsed model), so they return a DocView directly.

Variants

UnknownFormat

The format string handed to LeafDoc::new wasn’t one leaf understands.

Fields

name: String

Parse

leaf-core failed to parse source as the requested format.

Fields

message: String

Trait Implementations

impl<UT> ConvertError<UT> for LeafError

fn try_convert_unexpected_callback_error( e: UnexpectedUniFFICallbackError, ) -> Result<Self>

impl Debug for LeafError

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

Formats the value using the given formatter.

impl Display for LeafError

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

impl Error for LeafError

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
