Struct TryFromNumberError 

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

The error of a conversion of a Number to a primitive integer type that cannot hold it.

Examples

use a::math::numbers::{ByteOrder, Number};

let n = Number::new_from_i32(-1, ByteOrder::BigEndian);
assert!(u8::try_from(&n).is_err());
assert_eq!(i8::try_from(&n), Ok(-1));

Trait Implementations

impl Clone for TryFromNumberError

fn clone(&self) -> Self

Returns a duplicate of the value.

Performs copy-assignment from source.

impl Copy for TryFromNumberError

impl Debug for TryFromNumberError

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

Formats the value using the given formatter.

impl Display for TryFromNumberError

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

Writes what was wrong, in the words of the primitive integers’ TryFromIntError.

impl Eq for TryFromNumberError

impl Error for TryFromNumberError

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 TryFromNumberError

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

Equality operator ==.

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

Inequality operator !=.
