Errors returned by TextByteStream mutations.

Variants

InvalidUtf8

Raw bytes were not valid UTF-8.

Fields

valid_up_to: usize

The byte index up to which the input was valid UTF-8.

OutOfBounds

A byte index exceeded the stream length.

Fields

index: usize

The rejected byte index.

len: usize

The current stream length in bytes.

NotCharBoundary

A byte index split a UTF-8 scalar value.

Fields

index: usize

The rejected byte index.

InvalidRange

A byte range had its end before its start.

Fields

start: usize

The start byte index.

end: usize

The end byte index.

Trait Implementations

impl Clone for TextStreamError

fn clone(&self) -> TextStreamError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextStreamError

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

Formats the value using the given formatter.

impl Display for TextStreamError

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

Formats the value using the given formatter.

impl Error for TextStreamError

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 TextStreamError

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