Enum ProgressError 

#[non_exhaustive]
pub enum ProgressError {
    ZeroSequence,
    InvalidAmount {
        current: u64,
        total: Option<u64>,
    },
    InvalidText {
        field: &'static str,
        max_chars: usize,
    },
}

Invalid progress event.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ZeroSequence

Sequence numbers are one-based.

InvalidAmount

Current progress exceeded total or total was zero.

Fields

current: u64

Current quantity.

total: Option<u64>

Total quantity when known.

InvalidText

Text was empty, oversized, or contained control characters.

Fields

field: &'static str

Progress field.

max_chars: usize

Maximum accepted character count.

Trait Implementations

impl Clone for ProgressError

fn clone(&self) -> ProgressError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProgressError

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

Formats the value using the given formatter.

impl Display for ProgressError

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

Formats the value using the given formatter.

impl Error for ProgressError

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 ProgressError

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