Struct FieldError 

pub struct FieldError { /* private fields */ }

Why a field section could not be interpreted, naming the field and its position in the original section.

The name is the section’s own lowercase spelling of a declared or forbidden field. The name of an unknown field is untrusted input, so it is never included; nor is any value.

Implementations

impl FieldError

pub fn name(&self) -> Option<&'static str>

The field’s lowercase name, or None for an unknown field, whose name is untrusted.

pub fn position(&self) -> Option<usize>

The position of the offending field in the original section, or None for a missing field, which has no position.

pub fn kind(&self) -> FieldErrorKind

What went wrong.

impl Eq for FieldError

impl Error for FieldError

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
