Implementations

impl BRCodeError

pub fn invalid_format<T: Into<String>>(msg: T) -> Self

Create a new invalid format error

pub fn missing_field<T: Into<String>>(field: T) -> Self

Create a new missing field error

pub fn invalid_field_value<T: Into<String>, V: Into<String>>( tag: T, value: V, ) -> Self

Create a new invalid field value error

pub fn field_too_long<T: Into<String>>( tag: T, max_length: usize, actual_length: usize, ) -> Self

Create a new field too long error

Trait Implementations

impl Debug for BRCodeError

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

Formats the value using the given formatter.

impl Display for BRCodeError

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

Formats the value using the given formatter.

impl Error for BRCodeError

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 PartialEq for BRCodeError

fn eq(&self, other: &BRCodeError) -> 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.
