Error parsing human-friendly bandwidth

Variants

InvalidCharacter(usize)

Invalid character during parsing

More specifically anything that is not alphanumeric is prohibited

The field is an byte offset of the character in the string.

NumberExpected(usize)

Non-numeric value where number is expected

This usually means that either bandwidth unit is broken into words, e.g. M bps instead of Mbps, or just number is omitted, for example 2 Mbps kbps instead of 2 Mbps 1 kbps

The field is an byte offset of the erroneous character in the string.

UnknownUnit

Unit in the number is not one of allowed units

See documentation of parse_bandwidth for the list of supported bandwidth units.

The two fields are start and end (exclusive) of the slice from the original string, containing erroneous value

Fields

start: usize

Start of the invalid unit inside the original string

end: usize

End of the invalid unit inside the original string

unit: String

The unit verbatim

value: u64

A number associated with the unit

UnknownBinaryUnit

Unit in the number is not one of allowed units (in the binary prefix system)

See documentation of parse_binary_bandwidth for the list of supported bandwidth units.

The two fields are start and end (exclusive) of the slice from the original string, containing erroneous value

Fields

start: usize

Start of the invalid unit inside the original string

end: usize

End of the invalid unit inside the original string

unit: String

The unit verbatim

value: u64

A number associated with the unit

NumberOverflow

The numeric value is too large

Usually this means value is too large to be useful.

Empty

The value was an empty string (or consists only whitespace)

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

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