Struct UninitializedFieldError 

pub struct UninitializedFieldError(/* private fields */);

Runtime error when a build() method is called and one or more required fields do not have a value.

Implementations

impl UninitializedFieldError

pub fn new(field_name: &'static str) -> Self

Create a new UnitializedFieldError for the specified field name.

pub fn field_name(&self) -> &'static str

Get the name of the first-declared field that wasn’t initialized

Trait Implementations

impl Clone for UninitializedFieldError

fn clone(&self) -> UninitializedFieldError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UninitializedFieldError

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

Formats the value using the given formatter.

impl Display for UninitializedFieldError

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

Formats the value using the given formatter.

impl Error for UninitializedFieldError

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<&'static str> for UninitializedFieldError

fn from(field_name: &'static str) -> Self

Converts to this type from the input type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
